The Great McGinty

In a dive south of the border, bartender Dan McGinty (Brian Donlevy) stops a young man from committing suicide after a moment of dishonesty, and relates how a moment of honesty brought him down in a flashback. As a young man, McGinty joins a crooked political boss and rises from extortionist to alderman. Urged by the boss to marry his secretary to give respectability to his run for mayor, McGinty agrees -- only to fall in love with his wife and decide to do an honest thing for once in his life.
