Proud One (1956) / (Sen)

Robert Ryan (The Wild Bunch), Virginia Mayo (The Man Next Door) and Jeffrey Hunter (Custer of the West) make a dynamic trio in this "exceptionally well-presented" (Variety) tale of greed, betrayal and good old-fashioned justice on the frontier

When a flood of lawless gunmen invades his once peaceful town, Marshal Cass Silver (Ryan) knows it's up to him to force them out. But the only chance he might have is to gain the help of a gunslinger named Thad (Hunter), who wrongly believes the marshal is responsible for his father's death. To save the town, Silver will have to earn the aid, and trust, of a man sworn to send him to his grave!
