Cocaine Cowboys (1979)

Dustin (Tom Sullivan) is the leader of a rock band on the brink of super-stardom. Until now they have juggled their music career with cocaine smuggling. The musicians, and their manager Raf (Jack Palance), wish to sever ties with organized-crime, leave the drug world behind and concentrate on music. However they are coerced into doing one last job for the Mob. They lose the $2 million of cocaine, and find themselves marked men unless they can fulfill their obligations.
