A pair of desperate men plan to kidnap a wealthy heiress upon her arrival in France. Bud (Marlon Brando) and Leer (Richard Boone) grab the gorgeous girl (Pamela Franklin) at the airport in Paris. The limousine is driven down a deserted country road where the airplane's stewardess Vi (Rita Moreno) is in on the plan and helps the criminals switch cars. The quartet heads to a remote beach house where the girl's father is contacted with instructions for the payoff. When the girl tries to escape, Bud helps her from being roughed up by Leer, which makes the heroine junkie Vi jealous. Vi's brother Wally (Jess Hahn) goes with to the saloon where the drop-off is scheduled, but Wally is wounded in a gun battle with the bartender. He escapes and gives the money to Leer, who is finished having his sadistic carnal way with the kidnap victim. Bud once again tries to help the girl, and Leer tries to shoot everyone who stands in his way. The feature ends with a hard-to-fathom surprise in this violent story of murder, greed and love of money.
