The Strangers: Prey at Night
Mike and Cindy, Luke, and Kinsey, take a family trip to their aunt and uncle's trailer park to spend time together as a family before Kinsey leaves for boarding school. Cindy calls ahead and leaves a voicemail, informing Uncle Marvin that they were running late. As they arrive at the grounds and collect the keys to their trailer, they settle in and hear a knock at the door. Cindy answers the door to find Dollface—unmasked, but hiding in the shadows. She asks if Tamara is home. Cindy informs her she is at the wrong trailer, and Dollface leaves.

As the family sits down to play cards and implores Kinsey to join, Kinsey storms out and Cindy sends Luke after her to try and reach out. As Kinsey and Luke wander around the trailer park, they stumble upon a trailer with the door wide open. Inside, they find their aunt and uncle brutally murdered.

Mike and Cindy decide to go find the kids, whom they find in hysterics. Mike sends Cindy and Kinsey back to the trailer and follows Luke to find the bodies.

Mike and Luke find the bodies and the voicemail that Cindy left them, realizing that the killers heard the message and were waiting for them to arrive; Mike and Luke are then stalked by the Man in the Mask. Mike finds a revolver in the bedroom and finds the Man in the Mask gone. Mike and Luke run from the trailer back to their own and find Kinsey missing and Cindy dead. They drive their minivan around the grounds shouting for Kinsey, but one of the killers shatters the windshield with a thrown object, causing Mike to swerve and crash the minivan into a trailer. As they regain consciousness, Mike finds himself pinned into his seat by part of the trailer's porch and tells Luke to take the gun and find his sister. As Luke leaves, the Man in the Mask gets into the minivan with Mike, turns on the radio, and kills him with an ice pick.

As Luke runs out to the public pool, Pin Up Girl ambushes him, but Luke overpowers her and stabs her to death. Luke taunts The Man in the Mask by telling him he just killed one of his own. The Man in the Mask swings his axe at Luke, trying to stab him. Luke falls into the pool and grabs The Man in the Mask's axe, before tripping him into the pool. They fight. Luke is ultimately stabbed in the back and left to die. Kinsey arrives and pulls him out of the pool and sets off to find help.

Some time later, Luke is recovering in a hospital bed.
