Louis Leterrier's new Netflix thriller The Last House has viewers asking one question above all others: does the Delgado family make it out alive. The film, starring Greta Lee and Wagner Moura, seals its family of four inside their own Seattle home for five straight years — and ends on a moment strange enough to send fans straight to Google. Here's everything to know about how the Delgados survive, and what that final voice on the radio really means.
Key facts:
- The Last House premiered on Netflix on August 7, 2026, directed by Louis Leterrier.
- Greta Lee and Wagner Moura play parents Ann and Jason Delgado, sealed inside with their two kids.
- Short answer: yes, the Delgado family survives — and the ending hints they may not be alone.
- The film runs one hour and 52 minutes and is rated PG-13.
Quick Recap: What Happens in The Last House
The Delgados start out as an ordinary family — Jason (Moura), an out-of-work engineer, Ann (Lee), the family's steadying force, and their two kids, 12-year-old Graham and eight-year-old Ruth. Then a strange, unrelenting rainstorm seals every door and window of their house shut. Nothing can break through the barrier — not tools, not phones, not Wi-Fi. Within days, the family realizes their entire neighborhood is trapped the same way.
They soon work out that the rain isn't the real threat. Shadowy creatures are moving through the storm outside, and they're the ones keeping everyone locked in. A damaged chimney becomes the Delgados' lifeline, letting them catch small animals and collect rainwater through the opening, a survival trick the production nicknamed "chimney fishing."
Five years pass in what feels like a single cut. By then, the house has been stripped for parts, the family has learned to farm indoors, and Ruth — now played by Emma Ho rather than Riley Chung — starts to suspect the creatures outside aren't attacking at random.

The Ending Explained: Does the Delgado Family Survive
Yes — all four Delgados make it out alive, though it takes a change of heart to get there. When one of the creatures finally breaks into the house, it floods the family's water and crop supply, pushing them toward a last, desperate move. Jason hatches a plan to trap the creature. Ruth stops him from killing it instead.
That single choice changes everything. Once Jason puts down his weapon and lets Ruth try to communicate, the barrier keeping the family trapped finally lifts. The rain stops, the creatures retreat, and the Delgados step outside for the first time in five years into a world permanently reshaped by flooding.
With no other survivors in sight, the family boards a fishing boat and heads out to sea, calling over the radio to see if anyone else made it. Just before the credits roll, a static-filled voice answers back with a single word: "Hello." Who — or how many people — are still out there is left deliberately unclear.
Why the Creatures Finally Let the Delgados Go
The twist at the heart of The Last House is that the "invasion" isn't really an invasion at all. According to Leterrier, the creatures are ancient ocean dwellers responding to decades of environmental damage, not hostile visitors from somewhere else.
"They've been there way before us," Leterrier revealed to Netflix's Tudum in August 2026. His point is that humanity, not the creatures, is the real intruder in this story — and that the film's back half is about learning to share a planet rather than defend one.
That theme plays out through Ruth, whose ability to read the creatures as communicators rather than attackers is what finally convinces Jason to stand down. It's her instinct, not her father's instinct to fight, that saves the family — and eventually reaches whoever answers their radio call at the end.
Meet the Cast Behind the Delgado Family
Greta Lee plays Ann, the emotional backbone of the family, and has said she drew on the mothers in her own life to build the character. "Ann is a rock," Lee shared with Netflix's Tudum ahead of the film's release. She's described Ann as an ordinary woman capable of extraordinary strength once her family is in danger, a dynamic Lee has said felt personal to play.
Wagner Moura, known for Narcos and this year's The Secret Agent, plays Jason, the father whose instinct to control every threat has to bend before the family can escape. The role also demanded serious physical work. Moura has called the film's underwater sequences "the physically demanding thing I have ever done in my life," according to ComicBook.com.
Rounding out the Delgado family are Riley Chung and Noah Alexander Sosnowski as young Ruth and Graham, with Emma Ho and Gabriel Barbosa stepping in to play the siblings after the film's five-year time jump. Production designer Kevin Jenkins and survival consultant Megan Hine also worked closely with the cast to make the family's improvised survival tactics feel real onscreen.
Is There a Sequel to The Last House?
Nothing has been confirmed yet, but the ending leaves plenty of room for one. Leterrier has said other pockets of survivors likely exist beyond the Delgados, and that mysterious final "Hello" is deliberately left unresolved — the director has hinted the voice belongs to someone recognizable, without confirming who.
Moura, for his part, has spent time thinking about what comes next for the family he played for months on set. "I hope it's different for the characters of the film," he told CinemaBlend, reflecting on how the Delgados might rebuild in a changed, flooded world.
For now, fans will have to settle for theories. If The Last House performs well on Netflix's charts, a follow-up answering who's on the other end of that radio call wouldn't be a surprise.
