The Strangers: Prey at Night (2018)

After the events of the first film, the three masked strangers—Dollface, Pin-Up Girl and the Man in the Mask—arrive at a secluded trailer park in Kalida, Ohio, and murder middle-aged couple Sheryl and Marvin.

The next day, their niece Cindy and her husband Mike take a trip with their children, 18-year-old Luke and 16-year-old Kinsey, to the trailer park to spend time together before Kinsey leaves for boarding school. Upon the family's arrival, an unmasked Dollface knocks at their front door and asks for Tamara, but she is turned away by Cindy. Kinsey and Luke find their uncle's mutilated body inside another trailer. Dollface knocks a second time and is again turned away. Mike follows Luke to find the bodies, while Cindy and Kinsey return to the family trailer. They find their cell phones smashed before Dollface attacks them. They retreat to the bathroom, where Cindy helps Kinsey climb through the skylight and escape before Dollface breaks in and stabs her to death.

Mike and Luke find the voicemail that Cindy left for their uncle before arriving, realizing that the offenders had been waiting for them that whole time. After fending off the Man in the Mask, they find Cindy dead. They drive around, shouting for Kinsey, before the Man in the Mask causes their van to crash by throwing a cinder block on the car's windshield. Mike gets impaled with a wooden plank and gives Luke the gun. After Luke leaves to find his sister, Mike is killed by the Man in the Mask with an ice pick. Kinsey encounters Dollface and is stabbed in the thigh before being rescued by Luke. Luke hides Kinsey under a porch while he runs to the general store for help. He calls 911 but realizes he is not alone when Pin-Up Girl cuts the phone line and the call goes dead. Luke escapes to the swimming pool, where he overpowers and kills Pin-Up Girl. An angry Man in the Mask arrives and stabs him in the back, leaving him to drown in the pool; Kinsey rescues him before setting off to find help.

A deputy finds Kinsey but is quickly killed by Dollface. Kinsey shoots Dollface in the chest with a shotgun that she found in the deputy's patrol vehicle, removes her mask, and asks why she is doing this, to which she replies, "Why not?" Kinsey then kills her with a shot to the head. The Man in the Mask arrives and rams the back of the police SUV, causing his truck to get stuck in the collision. Then Kinsey notices a hole in both the vehicles' gas tanks and ignites the gasoline leak, blowing up both trucks. The Man in the Mask survives the explosion and chases Kinsey, but he is severely injured and pulls out a shard of glass that was impaled in his stomach, then he passes out. Kinsey flags down a passing truck, but the driver flees upon seeing the horrifically burned man sneaking up behind Kinsey with an axe. She jumps into the back of the truck as the man clambers on behind her. She strikes him in the head with a baseball bat she finds in the truck's bed, hitting him with such force that she knocks him off the truck. As the truck speeds away, the camera focuses on the man lying in the road, staring at the camera, lifeless.

Some time later, Kinsey is at a hospital with Luke. As she awakens, she is shocked and frightened at the sound of loud knocks and the doorknob turning, and she drops her cup of water.
