Pigs is a 1973 American psychological horror film co-written, co-produced, and directed by Marc Lawrence and currently distributed by Troma Entertainment.

A man named Zambrini lives in a rural California area and operates a small, isolated diner catering to local oil workers.

Into this mix comes a young woman named Lynn Webster, a stranger who comes to the diner looking for work and a place to stay.

After Ben takes her out in his truck and attempts to rape her, Lynn invites him back to her room at the diner and murders him with a straight razor.

Lynn seems to have only fleeting memories of her crime, and she continues making one-sided phone calls to her father, promising to return to him.

Once he makes contact with her at the diner, he reveals to Zambrini that Lynn has escaped from a mental institution; she is a dangerously disturbed psychopath due to being raped by her own father, whom she stabbed to death.

When he discovers that she is an escaped mental patient, he calls the diner to warn Zambrini before rushing out there to apprehend Lynn.
