Carlo Landa

Carlo, a young photographer, is making love with his girlfriend at the beach when he witnesses a murder being feebly staged to look like a car accident. Carlo takes incriminating shots of the murderers (the victim turns out to be the local public prosecutor) and attempts to sell them to various interested parties, including a gangster and a newspaper owner. One of the murderers' accomplices, a lowlife criminal, is gunned down by a black-gloved assassin, while another is stabbed to death...

Two Sicilian shopowners who live in Rome pick up some beatnik hitchhikers and the group gate-crashes their seaside villa. In the meantime the two men's wives smell something fishy going on and go to the villa themselves. To make things worse the place is also invaded by three prison fugitives who terrorize the lot.

After Cacopoulos manages to save himself from being hung on a false charge, he robs Cat Stevens and Hutch Bessy of a lot of money and steals their horses. This results in a merry chase and Stevens and Bessy become unwilling allies in Cacopoulus' revenge against the people who deserted him and framed him to get their money back.
