A woman is brutally strangled and her body stuffed into a suitcase in this otherwise rather frivolous low-budget thriller. The unfortunate woman is one Myra Duryea (Polly Ann Young), who has discovered that her husband Clark (Theodore von Eltz) and his equally unsavory brother Victor (Edward Emerson) are not the law-abiding jewelry salesmen they present themselves to be, but a couple of crooks. Arriving in San Francisco on the very day of the murder, Myra's sister, Gloria Watkins (Elaine Shepard), is told by Clark that his wife simply upped and left. Gloria's new friend, police officer turned cab driver Eddie Barton (Norman Foster), smells a rat, however, and begins an investigation. In desperation, Clark and Victor frame the nosy cabby in their next heist but Eddie manages to elude the law long enough to rescue an imperiled Gloria and bring the thieves to justice.
