Wild Seven is an intense drama that takes place in Arizona. After 21 years of wasted time in state prison, former convict Wilson (Robert Forster) wants to find peace of mind by means of revenge against his former crime partner Mackey (Robert Loggia), who was responsible for his conviction for a murder many years ago. Wilson designs a plan to frame Mackey in a bank robbery he was putting together with the help of a prison bus driver, Lee (Richard Roundtree), thus getting even with him for causing the loss of 20 years of his life. Although it was a good plan, things sometimes are unpredictable. It turns out that a gang of young and careless thugs wants to rob the same bank. They know nothing but drinking, doing drugs and women, and have no necessary skills when it comes to bank robbing, so all they will do is get caught and endanger Wilson's plan.
