LAPD Sgt. Joe Friday -- the equally straight-laced nephew of the famous police sergeant of the same name -- is paired up with a young, freewheeling detective named Pep Streebeck. After investigating some strange robberies at the local zoo and the theft of a stockpile of pornographic magazines, they uncover cult activity in the heart of the city and are hot on the case to figure out who's behind it all.

While attempting to seduce gorgeous lawyer Diane Lightson, wealthy gadabout Chris Thorne agrees to drive her to Atlantic City, N.J. But, when some reckless driving draws the attention of a deeply critical cop, they and the flamboyant "Brazillionaires" who tagged along end up in the court of a grotesque and vengeful judge, who has a special vendetta against the wealthy and erudite.
