Extremities is a 1986 American drama film directed by Robert M. Young and written by William Mastrosimone, based on his 1982 off-Broadway play of the same name.

While getting into her car one night, Marjorie is attacked at knifepoint by a masked assailant who forces her to drive to a remote location, where he tries to sexually assault her.

While at the police station, she is told that without a positive identification of her attacker, there is little they can do to help— and if he is found, it will be her word against his, and he will likely not face any criminal charges.

One morning, while Pat and Terry are away at work, Joe casually enters her home, claiming he is looking for someone who owes him money.

Marjorie removes the knife he previously used on her from his jacket, including the mail he stole, and threatens to castrate him if he does not admit the truth.
