Knock at the Cabin

Seven-year-old Wen arrives with her two fathers, Eric and Andrew, at a secluded cabin in rural Pennsylvania for a vacation. Wen enjoys her time in nature, focusing on her passion for collecting and documenting grasshoppers.

Wen encounters Leonard, a mysterious stranger who approaches her while she is outside. Leonard claims he needs help from Wen and her parents to prevent a global catastrophe, piquing her curiosity with his unusual appearance and demeanor.

As Wen speaks with Leonard, she opens up about her life and family dynamics, explaining why she calls her dads by their first names. This conversation reveals Wen's pride in her unique family situation despite facing judgment from peers at school.

During their conversation, Wen shares her personal story of resilience, talking about her cleft lip surgeries from birth. This moment deepens the connection between Wen and Leonard, but it soon turns ominous.

Alarmed by Leonard's suggestion of tough choices ahead, Wen rushes back into the cabin to alert her fathers. The family quickly barricades themselves as Leonard and his three associates begin demanding entry, intensifying the atmosphere of fear.

Despite the family's efforts to secure themselves, Leonard and his crew forcibly break into the cabin, brandishing makeshift weapons. The family is subdued, and chaos ensues as they face the intruders.

Leonard reveals that they have been driven by disturbing visions to find Wen's family. He presents a harrowing ultimatum: to avert an impending apocalypse, one of them must be sacrificed.

In a shocking turn of events, the intruders sacrifice Redmond right in front of the family, an act that triggers catastrophic events outside. Eric witnesses blinding light as news reports begin to show the chaos unfolding across the globe.

With the counter ticking, Leonard gives the family until sunrise to decide on their course of action. Meanwhile, Andrew reflects on the possibility of Redmond being a former assailant, heightening the tension in the situation.

The following day, tensions boil over as the group sacrifices Adriane, resulting in the release of a lethal flu strain worldwide. Eric begins to believe that they are faced with the Four Horsemen of the Apocalypse.

Faced with the loss of life and destruction, Eric volunteers himself as the next sacrificial choice to secure a future for Wen and Andrew. His decision reflects an emotional depth and a desperate wish for his family’s survival.

In a heartbreaking moment amidst the chaos, Andrew reluctantly pulls the trigger on Eric, marking the shattering of their hopes. This act seals their fate and deepens their emotional scars.

After the violence, the family manages to escape toward a diner, desperate for safety and clarity. As they drive away, they catch news reports that suggest the disasters, while terrible, may be coming to an end.

Even as the world outside begins to stabilize, the family is left with deep emotional scars from their harrowing experience. The events they endured stain their bonds and challenge their understanding of love and sacrifice.
