With the cops completely stymied, Cliff (Jack Betts) swears to track down and punish the man who killed his kid brother with a hamburger laced with ground glass in this seedy exploitation flick from the beatnik era. But when the trail leads to twisted psychopath Nico (Peter Falk) and his violent gang, straitlaced Cliff must rely on bohemian gal-pal Ellie (Barbara Lord) to help him bring Nico to justice.
