All the Boys Love Mandy Lane Part II

Plot Summary
The film begins as high school student, Mandy Lane, successfully frames her former best friend, Emmett, for the murders of her friends. She helps Garth, whom she has taken a romantic interest in. Mandy drives him to a nearby hospital, where the two are helped by the staff. As Mandy is being cared for, her cousin Jen arrives and reveals that Chloe survived her wounds, but that she is currently unconscious and in surgery for the stomach wound she suffered.

Unbeknownst to Jen, Jo, or Garth, Chloe had been attacked by Mandy, who left her for dead. Realizing Chloe's survival could mean imprisonment, Mandy enters her hospital room and attempts to suffocate her to death, but Chloe fights back. Mandy overpowers her and suffocates her to death. Her death is ruled as an accident, while Sheriff Cassidy begins to suspect that more than one person helped Emmett in the murders. He asks one of his officers, Deputy Williams, to watch over Mandy and her friends for him.

While at school, Mandy is called out of class to be interviewed by Cassidy, who reveals to her that evidence suggests more than one person was responsible for the murders at Red's family's ranch that night. Mandy tells him that she doesn't know who could be involved, before he releases her back to class. While walking back to class, Mandy bumps into a girl named Karla, who reveals that she was also a friend of some of their deceased classmates and invites Mandy to a vigil the students are having at a nearby farm. Mandy tells her Jo about this, but Jo is nervous to let Mandy go alone, so she asks Jen to accompany her.

When Friday finally rolls around, Mandy and Jen leave for the farm where the vigil is being held. Mandy and Jen arrive at the farm, where they discover a small group of students consuming alcohol and smoking marijuana. The group is composed of Jen's boyfriend, Andrew, Jessica and Megan, who were friends of Chloe's, and Drew's friends Luke and Ryan. As the night wears on, the friends retreat back to the farmhouse, leaving the fire to burn up outside. The group plays a game of strip monopoly, before Luke reveals there is a nearby lake they can go swimming in. She takes off for the lake, where she climbs in naked. Luke follows after her, but he is attacked by an unseen assailant, who impales him through the skull with a Bowie knife.

A dying Luke makes his way to the shores of the lake, where he falls in. Megan sees his body and climbs out of the lake, running back towards the house, when she is suddenly caught in a mesh. She runs into someone she knows and begs them for help, before they kill her by stabbing her in the stomach. The figure then pushes her to her death down a steep embankment, leaving Megan to die of her wounds. As night falls, a storm begins outside. Concerned, Jessica goes to search for her friends in the rain.

As she is searching, she discovers Luke's body floating in the lake. Believing him to have drowned, she swims over to his body where she discovers his disfigured face. Horrified, Jessica attempts to escape back to the house to alert the others to the murders, but she is ambushed by the murderer. The assailant throws gasoline on Jessica, before lighting her on fire. Jessica's screams go unheard, before she collapses and burns to death. The murderer then proceeds back to the house, where they watch as Mandy sleeps, stroking her face.

Early in the morning, Jen, Mandy, and Andrew awaken to discover that Jessica, Megan, and Luke still have not returned. Karla is also missing. Andrew discovers Megan's bloody necklace, along with a message "Look what you made me do." written in blood on the bathroom mirror. A wounded Karla appears, having been attacked by the murderer while searching for their friends. She leads Andrew to Jessica's burnt up body, before she attacks him with a Bowie knife, revealing herself as the killer. Karla stabs him in the chest, before returning to the house alone.

She tells Jen and Mandy that she is the murderer, before revealing to Jen that Mandy was actually behind the murders at Red's ranch, while Emmett was only working as her accomplice. Jen asks Karla why she is avenging Emmett's death at Mandy's hands, and Karla reveals that she was Emmett's half-sister and that Mandy did not deserve him. Karla stabs Jen in the stomach numerous times. As Karla murders Jen, Mandy is able to free herself, before running out of the house with Karla in hot pursuit. She runs into the woods, where she falls down an embankment and into the lake, discovering the bodies of Luke and Megan.

Mandy is able to flag down a passing motorist, who promises to help her. However, Karla appears in her own vehicle and slams into the truck, knocking Mandy unconscious momentarily. She awakens to the sound of gunfire, as Karla murders the motorist. Mandy releases the emergency brake, sending the truck down the embankment. Karla dies when she is struck by branches. A wounded and bloody Mandy emerges from the wreck, before climbing up onto the highway where she flags down a motorist for help as the film ends.
