One rainy night, Richard Bone's (Bridges) car breaks down in an alleyway. He spots a large, mysterious car in the distance. A man dumps something into a garbage can. At first, Bone thinks nothing of it and proceeds to meet his friend, Alex Cutter (Heard). The next day, a young girl is found brutally murdered in the same alleyway where Bone abandoned his car. He becomes a suspect. When Bone spots the man he thinks is the murderer in a parade later that day — local tycoon J.J. Cord (Stephen Elliott) — Cutter begins to take an interest in the mystery that unfolds. His interest soon becomes a conspiracy theory that develops into a troublesome investigation with his skeptical friend and the dead girl's sister (Ann Dusenberry) along for the ride.
