Hell Fest

At Hell Fest, a traveling horror theme park, a masked man known as "The Other" kills a woman and hangs her corpse in the maze so it blends in with the props.
On Halloween night, Natalie goes to the theme park with her best friend Brooke, Brooke's boyfriend Quinn, Brooke's roommate Taylor and her boyfriend Asher, and Brooke's friend Gavin, who likes Natalie. Natalie and Brooke's friendship has been strained due to living far apart and Natalie's distaste for Taylor. On arriving at the festival, the girls run into a terrified woman trying to hide from the Other. Natalie, thinking this is part of the park experience, points out her hiding place. The Other kills the woman in front of Natalie. Natalie thinks the murder seemed too real to be a normal attraction. The group dismisses her fears until Brooke catches the Other stealing Natalie and Gavin's pictures from a photo booth.
While the others are gone, The Other kills Gavin first, crushing his skull with a mallet. Natalie goes on a ride alone while the rest of her friends pair up. The ride breaks down, and she is approached by a man who appears to be the Other. This is part of the ride, however, and the group discovers that park employees wear a mask similar to the Other's.
The group splits up and The Other finds Natalie but she escapes. Asher is killed when the Other stabs him in the eye. The friends regroup, but the Other traps Natalie in the bathroom stall. She escapes and tries to warn park security but they dismiss the attack as part of the park experience.
Natalie, Brooke and Quinn find Taylor has volunteered to take part in an attraction where she will be beheaded by a guillotine in front of a live audience. Park security prevents Natalie from stopping the show when she recognizes the Other's boots on the executioner. The stage curtains close and the Other approaches Taylor who, assuming he's an employee, asks to be let out. As she becomes increasingly alarmed, the Other straps her in tighter and raises the guillotine. After pausing to silently stare at her, he releases the guillotine, only for it to be revealed that the drop was done to a dummy, as would be originally intended for the show. Immediately afterwards, the Other sets the blade up for real to cut off Taylor's head. However, Taylor escapes when the blade fails to fully cut through. Freeing her hands, she escapes, and begins running through the festival screaming for help. The Other catches up with her and slashes her face while surrounded by festivalgoers. Quinn, hearing her screams, runs towards the two. Just as he reaches them, the Other stabs Taylor in the stomach. Before Quinn can react, the Other turns around and fatally stabs him as well.
As panic ensues in the park, The Other traps Natalie and Brooke in a maze. The girls are separated, and the Other corners Brooke. Natalie stabs the Other in the gut before he can kill Brooke. Police barge into the maze to save them and capture the killer. The Other, however, has escaped, and drives to his suburban home. He places his mask and the pictures of Natalie and Gavin that he stole into a cabinet with other masks and trophies from his previous kills. The Other's young daughter wakes up to greet her father, and he gives her a stuffed animal from the park.
