Michael McBain (Bo Svenson) witnesses a mob killing and agrees to testify. That's when crime boss Vincent Karbone (John Colicos) and his men turn up the heat, intimidating McBain's wife (Belinda Montgomery) and children. With the police unwilling to help, McBain realizes he's better off defending himself -- by striking back. Svenson builds on his Walking Tall persona in this hard-hitting revenge drama from director Bob Clark.
