Gum-chewing frizzy-haired gold-digger Marie Skinner cooks up a scheme with her lover Babe Winsor, a jazz hound, to fleece a portly, middle-aged real estate tycoon, William Judson. Marie moves into Judson's apartment building and contrives to meet and seduce him, plying him with compliments, music, swoons, décolletage, and batted eyes. When his loyal wife (and their two children) see him out catting with Marie at a night club, mom's devastated and confronts him. He moves out. Babe wants Marie to sell Judson worthless bonds. Will mom commit suicide? Will sis shoot the floozy? Will pops figure out he's being a fool?
