Handsome young plumber Jack Staley (Lee Philips) supplements his income by blackmailing his female customers, threatening to tell their husbands of their "illicit" romances. But Staley's career as an extortionist comes to a formidable roadblock when he tries the same shakedown on Margot Brenner (Phyllis Thaxter). It turns out that Margot has a bit of a larcenous streak as well...and she's just a shade smarter than both Jack and her husband (played by Carl Betz). ~ Hal Erickson, All Movie Guide
