Matt Brogan, wrongly imprisoned for the murder of his wife and son, escapes to go in search of the real killers whose evidence brought about his conviction. In the remote town of Alvorado, a hideaway for outlaws on the run and the power base of the Mc Lagan family, Brogan links up with lawman Jed Harding and the pair set out to rid the territory of the rule of fear. When hot-headed Roy Mc Lagan sets out to burn the farmers from their homes, Brogan and Harding persuade the locals to fight back. But to bring an end to the killings Brogan has to call on help from an unlikely source – Alex Mc Lagan, the man he had vowed to kill.
