Toby and Butch are a couple of bumbling crooks who get a truck driving job hauling insecticide from Italy to France. Unbeknownst to the clueless duo, they're really smuggling guns. A group of equally inept mobsters try to steal the guns to no avail.

Based on the adventures of the hero Tex from the comic strip by Bonelli. An interesting spaghetti-western/fantasy movie that blends magic and mythology with six-guns and stagecoaches.
