Bob Hughes is the leader of a "family" of drug addicts consisting of his wife, Dianne, and another couple who feed their habit by robbing drug stores as they travel across the country.
Convicted corporate criminal Howard engineers a prison break as he and a number of fellow inmates are being transferred to a new facility. The escapees storm a shopping mall and take a group of shoppers hostage (after killing many more of them) before making their demands. Only Rudy, a former mercenary and brother of one of the fugitives, can take out the criminals before more of the hostages die.
