Episode 14 of the 1960s feature-length American western series following the adventures of Marshal Jim Crown (Stuart Whitman). When some bandits bushwhack an army payroll wagon, one of their band, Bo (J D Cannon), is injured by a dynamite charge. Leaving him for dead, the rest escape with the money and Bo is arrested and jailed for several years. Desperate to get even, Bo kills a Texas deputy, steals his papers and arrives in Cimarron where he gets a job working for Crown who is unaware of his true identity. Now, with the law on his side, Bo starts hunting down each member of his former gang who are living the good life that should have been his. It's not long before Angus MacGregor (Percy Herbert) realises that there is something suspicious about the new deputy and Crown must put a stop to his ruthless killings before he gets even further out of control.
