Top Gun (1955)

Gunfighter Rick Martin returns to his hometown of Casper, Wyoming to learn of the fate of his mother and to warn the town of an impending raid by the Tom Quentin gang. The townspeople however reject him, afraid that his gunslinging past will cause new trouble. Rick learns that his mother did not die of illness but was murdered, and he comes to suspect the town's leading citizen -- a man now engaged to marry the woman Rick loves.
