In this futuristic action drama directed by Lewis Teague, Frank Warren (Rutger Hauer) is a man accused of stealing millions of dollars worth of gems. In prison, all the inmates wear collars which are electronically joined to those of an unknown partner. The collars will explode if either partner gets more than 300 feet away from the other. Warren is determined to escape, however, and finds that his partner is Tracy Riggs (Mimi Rogers). They plan and execute an elaborate escape and head off to search for the stolen diamonds. But members of Warren's former gang pursue them.
