Netflix’s “The Last House” follows Ann and Jason, and their children, after an unexplained rainfall seals them and their neighbours inside their homes behind an apparently indestructible watery barrier. The film turns this confinement into a survival story, with the family enduring isolation, dwindling supplies and increasingly threatening creatures outside, while the cause of the disaster remains a central mystery.

Weeks become months, then years: the family initially survives on stored food, but faces worsening tensions, a neighbour’s terrifying warning that “everyone is dead”, and the loss of their dog. After power fails, Jason devises a way to bring animals into the house for food and Ann creates an indoor garden; five years later, their home has become a farm amid an overgrown, deserted neighbourhood, though the family remains deeply unhappy and the surrounding ground is eroding.
