Pretty Poison

Sinopse

Dennis Pitt is a disturbed young man on parole from a mental institution who becomes attracted to teenager Sue Ann Stepenek. He tells her that he is a secret agent, and takes her along on a series of "missions". Things, however, turns out disastrously when Dennis takes Sue Ann along to sabotage a factory on imaginary orders from the CIA, during which the couple encounters the factory's night watchman, as Sue Ann knocks the watchman unconscious and then drowns him. While Dennis is wracked with guilt over both what he has done and what he has allowed to happen, Sue Ann is excited by the "adventure" and entreats Dennis to run away with her to Mexico. First, however, they have to get rid of her disapproving mother. However, as the couple return to Sue Ann's home for her clothes and are interrupted by the arrival of Mrs. Stepanek, Sue Ann realizes that Dennis is incapable of actually killing a person, so she shoots her mother and orders Dennis to dispose of the body. But instead, he calls the police.
