Houston, Texas, 1986: 14YO Laurie Tremblay is murdered. The case goes cold, and years pass with more bodies discovered, without any clues on who the killer is. Meanwhile, young Tiffany Shore moves in with her dad after her parent's divorce. She starts to realize he is not as fun as she remembered. More and more controlling, he makes a habit of locking his daughters inside the house when he leaves. As his behaviour becomes increasingly strange and overprotective, the Tourniquet Killer claims more victims: surviving her dad’s sudden rages will actually be the key to solving the terrifying serial killer case.
