Tara is a teen outcast in school and neglected by her mother at home. While riding her bike back home, she is drugged and brought to a deserted house by the pianist Anton, and his wife, Judith. They lock her in the basement where she meets their son, Johnny trying to commit suicide. Tara discovers the couple lost their son in a lake years earlier, and has made a pact with a demon to bring him back... in exchange for the sacrifice of 12 teenagers, and Tara is the last one.
