The Last House Ending Explained: Why Can’t They Get Out of the House?

Directed by Louis Leterrier, ‘The Last House’ is a horror thriller film in which a family’s house becomes their haven and their prison all at once. A married couple, Ann and Jason, live with their two kids, Ruth and Graham, in a nice suburban neighborhood. One day, in light of some heavy rainfall, the family finds that every exit from their house, windows and doors alike, has been mysteriously sealed shut. Moreover, it seems like the entire neighborhood, and possibly beyond, is undergoing a similar experience.

Thus, effectively trapped within their own home, the Delgado family has no choice but to continue fighting for their survival, hoping that something will eventually give. However, days turn into weeks and soon years. Yet, they soon discover that dwindling supplies and cabin fever aren’t the worst of their worries. It seems like the torrential rain brings with it some mysterious predatory creatures, who might just be responsible for humanity’s current predicament. SPOILERS AHEAD.

The Last House Plot Synopsis

On a nondescript Tuesday morning, heavy rainfall seems to take over the entire world despite predictions of sunny weather. The Delgado household, including parents Ann and Jason, their kids, Ruth and Graham, and the family dog, Cassidy, makes plans to go shopping for a Christmas tree. However, they soon realize that some invisible force has sealed shut all the doors and windows of the house. Around the same time, the internet and the phone signal both go down, leaving no lines of communication open. Even when the father tries to break open the windows, the cracks somehow refuse to budge. Outside, every household in the neighborhood seems to be stuck in the same predicament. Initially, everyone tries to cope with the situation, hoping everything will soon go back to normal.

When the situation carries on to the next day, the Delgados try to remain level-headed. They ration their food and try to instill a routine by assigning chores and holding school hours for the kids. Soon enough, a month passes with no change, bringing upon a bleak Christmas for the family. Yet, the real horror begins to descend when one night, the family watches Susan, a neighbor who was locked out of her house, running for her life from some unknown creatures that come in with the rain. After banging on their window for help to no avail, she warns the Delgados to hide before being swept away in a blinding white light. This incident compels the others to finally give some credence to Ruth’s account of seeing “rain walkers” outside the windows.

Although they still don’t know anything about these creatures, they begin to cover up the windows during rain to avoid detection. In time, things get even worse when Cassidy’s heart medicine runs out, pushing Jason to put down the beloved family pet with his emergency gun. Afterward, he has to do the unthinkable and butcher the dog up to be frozen, in preparation for the increasingly likely possibility that the rain would outlast their emptying food supplies. Three months later, their resources have entirely dried up to the point where death by starvation becomes a real threat. Ann is almost on the verge of giving up when Jason is struck by a last-ditch idea. The house’s chimney has been sustaining a crack all this time, which had earlier allowed the cover to cave in, creating a tunnel to the outside world.

While the chimney was too narrow for anyone to go through, Jason was able to needle a makeshift trap through and into the backyard, with the hopes of catching some of the wildlife outside. After a few failed prototypes, the trap finally works, returning sustenance and hope back into the Delgados’ lives. Once they have secured a sustainable method of procuring food, they’re also able to efficiently give Ann’s home farm to grow. Even as electricity and running water go out, the family continues making adjustments and surviving. Thus, five years pass like this. However, this perpetual house arrest continues to weigh heavily on the family. One day, things get worse when a rain walker from outside somehow cracks open the front door and comes prowling into the house. Although the Delgados manage to survive the night, the creature poisons their plants and freezes their drinking water, asserting that survival for the family is not only impossible but also futile.

The Last House Ending: Why Can’t They Get Out of the House?

Initially, during the early days of their entrapment, the Delgados and their neighbors had many theories about what exactly it was that was keeping everyone inside their houses. Some wonder if it is a government experience, while others pitch the idea of aliens. For Jason, understanding their situation perpetually takes second place to surviving it. Even as the rain walkers, or visitors as they begin to be called, come into the picture, the father never dwells much on their origin. On the other hand, young Ruth remains fascinated with understanding these creatures that seem to have taken humanity hostage. The rain is the foremost piece of the puzzle. The rain that takes over the world on a Tuesday is unlike any other.

The water seems to behave in strange ways, moving freely and coalescing independent of their physics. This rainwater is the exact thing keeping the humans inside their homes. The water collects and blocks off every orifice in a home, doors, windows, and everything, creating a kind of seal that is near-impossible to break. However, the rainwater isn’t behaving so strangely on its own. In some way or another, the strange rain is directly connected to the visitors that prowl the streets, hunting humans. Although many, including Jason, have an immediate compulsion to believe these creatures must be extra-terrestrial in nature, they’re actually Earth’s natives. Ruth, who is untethered by skepticism, is the first one to pitch this theory.

Ruth believes that the visitors could have emerged from the deep, largely unexplored parts of the sea that dominate the Earth. These creatures have existed on Earth for thousands of years. However, after allowing humans to desecrate their home planet with global warming and pollution, they have finally decided to take the entire world for themselves. The torrid rain helps them traverse onto the human-populated landmasses, slowly but steadily marking it all as their terrain. By trapping the humans inside their houses, these creatures are asserting their ownership over the planet. Much like how Graham keeps a few fish in a tank in his room, the Delgados and the rest of humanity have also now become trapped, free to be hunted at the whim of the dominant species.

Do The Delgados Escape?

The Delgados manage to survive inside their house for five years, outlasting most, if not all, of their neighbors. The fact that their house is experiencing structural damage, on account of the crack in the chimney, ultimately ends up becoming their saving grace. The chimney becomes their one connection to the outside world, which allows them to use its resources for their own benefit. When they run out of food, they’re able to hunt through their “chimney fishing” method. Similarly, when the water runs out, they can collect potable drinking water through the open chimney. Nonetheless, even after everything, the Delgados can only continue to survive rather than truly live. Graham feels the weight of this predicament severely and even tries to escape through the door when one of the creatures enters their home.

Shortly afterward, Ruth gets bitten by a ferret and sustains an infection, requiring antibiotics. Despite the hopelessness of the situation, Ann and Jason manage to find a solution by digging a tunnel through the underground sewer system, which connects the different houses in the neighborhood. Yet, when the mother goes on the quest to secure medicine from the Richardsons’ home, she ends up briefly encountering an angered one of the creatures. As a result, even after she manages to make it back home and save Ruth’s life, danger looms over the family. They have effectively earned a giant target on their backs with the rain walkers, who have been alerted to their presence in the house as prey waiting to be hunted. At first, Jason comes up with a bleak solution that requires him to be sacrificed to give his family a chance.

Nonetheless, Ann and Graham make him realize that the life they had been living so far isn’t sustainable. The house may provide them safety and survival, but they can’t live on the promise of seeing another day alone. They need to finally escape from their situation. The fact that the creatures can open the doors only further fuels their belief that rotting inside the house isn’t their only option. As a result, the Delgados finally come up with a plan to bait the rain walkers and use them to orchestrate their escape. Even though the family manages to catch the attention of one of the creatures, who enters their house with a flood of saltwater, they aren’t quite able to pull off the entire thing. In the end, Jason manages to inadvertently trap a creature with his harpoon, threatening the other being to open the door. Much to his surprise, the creature listens to his demand once he drops his weapon.

Why Does the Creature Let the Delgados Go?

At the end, when Jason faces off against the creature, his immediate instinct is violence and aggression. The rain walker is harpooned and trapped, putting the humans at an advantage over it for the first time ever. As a result, the father tries to threaten his way to freedom. He demands that the creature open up the house doors, finally letting him and his family escape. However, it isn’t his threat that actually works. Now that their roles have finally reversed, Jason has an epiphany about the entire situation that opens his eyes to a different reality. The rain walkers aren’t some invaders that are trying to take the planet from the humans.

As the father finally chooses to listen to what his daughter has been saying this entire time, he realizes the world belongs to the creatures as much as it does to him and his family. By surfacing to the terrain, the creatures have simply flipped a power dynamic that has allowed the humans to reign, hunt, and govern over other animals all this time. Even so, in his specific situation, there doesn’t need to be a prey and a predator. Alongside theorizing on the rain walkers, Ruth has also been consistently insistent that she has spotted a friendly creature outside. While the other creatures view humans as inferior prey to hunt, there is a possibility for this dynamic to change. However, threats on the edge of a blade isn’t the way to achieve such an outcome.

If Jason wants the creature to allow his family a chance at survival, he has to extend the same to it. Therefore, he drops his own weapon and frees the rain walker from his bonds. This act of mercy becomes the earliest tool in bridging the gap between humans and the new inheritors of the Earth. Once freed, the creature reciprocates this kindness and opens up the door to the Delgados’ house, finally giving the family a chance to escape. This interaction between the two showcases that, despite their differences, the two are in fact very similar to one another. Both the rain walkers and the humans are fighting for their survival. They both view the other as a danger and a threat to their future, which is why they easily turn to violence. Yet, it’s the act of mercy and empathy that truly helps them in the end.

Does the Rain Stop? Why?

Once the Delgados finally escape their house, the wrecked building finally collapses as the structure gives out. Even when an immediate danger surrounds them in the form of multiple other rain walkers, the friendly one corrals the others away from the human family. Shortly thereafter, the unforgiving rain finally stops. Once the water clears, the creatures have no choice but to retract anyway, allowing the Delgados some time to recuperate. After years trapped in their home, the four of them know exactly what kind of future they want. Their neighbors’ boat, placed in their front yard, became their first stop.

Now that the world has changed, it is accommodating the rain walkers rather than the humans; the Delgados have no choice but to adapt. Fortunately, the family of sea-lovers has no problem with building a new life for themselves out in the sea. They name their boat after Cassidy, the dog, and sail the world together, learning to co-exist with the rain walkers. The rain, the torrid kind, also stops, never to return again, as the creatures commit to an attempt at co-existence as well. As such, clear skies become a symbol of hope and possible interspecific friendship. The Delgados sail for many years before another kind of hope finds them. On the radio, they finally hear another human’s voice, signaling the possibility of civilization and an emerging human community.
