Foster is a 1920s gangster punk working his way up a bootlegging syndicate. He gets his nickname from his ruthless use of his tommy gun, which he dubs his "music box." Patten, his pregnant wife, eventually leads him to a downfall. This is a formula gangster flick, with cliched situations
and stereotyped characters. The direction is efficient, however, giving some polish to an otherwise standard piece. The cast gives the film a little soul as well with some spirited performances.
