A woman with a ponytail is limping through the woods to get away from a muscle man. She thinks she is clear from danger, but she limps right into the arms of danger, and is tackled by the man.Next, we see Jenny at a party. She is bonding with a guy named Drake, who is in a band. Jenny is impressed and calls him a "Renaissance Man" He invites her to his show and gives her a flyer. Jenny realizes that she missed curfew and tries to leave the party, but she runs into car trouble and calls her mom who says she'll be there in 10 minutes. Drake appears and helps her fix the car and continues to invite her to his show. They have a romantic moment, but Jenny's mom, Laura, interrupts the mood and is very worried. Things between the mother and daughter are tense since Jenny's father died. Laura is overprotective but leaves for a work conference.With her mom out of town, Jenny drives to Drake's show alone. When Laura calls to check on her daughter, she is horrified to learn Jenny is driving so far. It gets worse when Jenny swerves off the road and hits a pole with Laura on the phone. Jenny hits her head on the steering wheel, and Laura is screaming into the phone, asking if everything is okay. Jenny calls 911, and Laura decides to stay on the phone until help arrives.An ambulance pulls up, and a guy checks Jenny for a concussion while the other guys pulls up Jenny's luggage from her car, to which she objects. Then she is sedated by injection by the guy who checked her for concussion. She wakes up in a room full of dolls. There is a device strapped to her leg which causes severe pain when triggered by a remote which Clyde (one of the brothers who kidnapped her) holds. He tells her that he faked being an EMT, gives her the dress to put on, and takes her to meet Momma.Momma (Played by Acadamy Award Nominee, Cathy Moriarty from Raging Bull) thinks that Jenny is her daughter Lizzie and is trying to recreate her family. When Jenny shows Momma a picture and calls them all insane, Momma slaps Jenny and tells her not to use that word. Momma and the 2 sons then pray at the table holding Jenny's hand too and then eat fried chicken like a typical family while Jenny looks on. She then pulls a knife on them and tries to escape frantically. The family doesn't even stop eating; they totally ignore Jenny's hysteria. The doors and windows are all locked. Momma soothes Jenny in her bed and tells her she is glad she is finally home. Momma is more of a helicopter mom than Laura.Meanwhile Laura is searching for her daughter with not help from the police who thinks it's another runaway case.Jenny finds the diary of the real Lizzie that says that Momma did not approve Lizzie's boyfriend Tommy, and decides to run away.The journal inspires Jenny to also runaway. She hits Clyde in the face with a frying pan, grabs hold of the remote that triggers her device tied to her ankle, and runs off into the woods. Jenny hits an electrical fence and is disabled with jolts of electricity which auto triggered the ankle device, causing her to collapse. Jenny is brought back to the house and forced to continue to be Lizzie.Jenny finds some old dispatch equipment and learns from Lizzie's nicer brother Guy that there has already been one replacement, Lizzie. She didn't make it because Momma put her in the basement with the rats.Meanwhile Laura and Drake put up missing person flyers and go from house to house in the area in which Jenny disappeared. Laura shows up at the house where Jenny is held. with a missing person flyer. Momma and Laura are face to face. Momma plays it cool but is put off by Laura's questions. Jenny is held at knife-point by Clyde to keep from screaming for help. Then Momma forces Jenny to record a voicemail to call off Laura from searching for her saying she's happy at where she is and not to look for her She includes one coded message. "Tell dad I said hi." Laura knows she was coerced to leave the message.Jenny starts playing into the role of Lizzie and makes amends for Lizzie's mistakes. She also appeals to Guy and attempts to seduce him. Jenny kisses him, and Momma catches them in the act. Momma drags Guy by his hair to the basement and threatens to throw him in. Whatever is down there, he is terrified.Without the sheriff's help, Laura goes to Drake and gives him the voicemail audio. Drake determines that the voice mail was recorded in a house near a train. Drake finds the home and the fake ambulance. He sees his flyer in the truck and knows that Jenny is in the house. Drake knocks Guy out with some wood, steals his keys and sneaks into the house. He frees Jenny, and they run off. (Before fleeing the house, Drake unlocks Jenny's ankle device, using the bunch of keys he took from Guy, and throws it away. So when Clyde tries to activate it with remote, it does not work on her.) But Drake is caught by in a bear trap. He begs Jenny to leave him, and she runs to his car. Drake gets killed by Clyde with a rock, and Guy stops Jenny from driving off.Jenny is thrown in the basement because Momma realizes that she is not Lizzie. In the basement, Jenny finds a trunk with Lizzie's body in it.Laura finds a similar missing person case and goes to talk to the mother. The mother gives Laura a gun and tells her to avenge her daughter's death. Laura pretends to be a teen in trouble to lure Jenny's kidnappers. It works. Guy and Clyde get in the ambulance and drive to the scene. When they arrive and find nothing, they leave, leading Laura back to the house.Set on saving her daughter. Laura locks Clyde in a garage and gets out her gun. She forces Guy to show where her daughter is, and take her out of the basement. Jenny tells Guy that Lizzie's body is in the trunk downstairs. (All this time Guy was under the impression that Lizzie has eloped with his boyfriend, but Clyde knows that she was killed by Momma, who still claims it was an accident) He is devastated.Clyde breaks himself out of the garage, attacks Laura and starts strangulating her. Jenny runs into the house and collect the ankle collar and saves her mom by putting the collar on Clyde and turning it full blast. Momma grabs the gun and does her villain monologue while holding mother and daughter at gunpoint. Guy goes to the basement and finds the remains of Lizzie and knows that his momma killed Lizzie. He jumps between Momma and the couple and they struggle while Laura and Jenny runs off. We hear a gun go off. Momma shoots Guy dead.The police finally show up. (Laura has texted the fake ambulance address to the detective) Momma is taken into custody as Jenny and Laura are reunited. They, obviously, decline paramedic treatment.Finally, Jenny and Nicole (Jenny's friend) are off for college.
