Synopsis: In the American Southwest, Jim Kane scrapes a living as a cowboy. The trouble is, something always seems to go wrong. His latest job concerns transporting a herd of cattle from Mexico into the United States for shifty businessman Bill Garrett. But Kane knows it won't be easy -- he only just lost money when the horses he tried to bring over were quarantined by customs. Desperate for pay, he goes ahead anyway, teaming up with his old partner, Leonard.
