When millionaire-about-town Rex Walton (Ivan Brandt) mysteriously vanishes on the eve of his wedding, a chain of strange, violent events is set in motion. Intrepid Joan Walton (Linden Travers) assists Inspector Dicker (John Stuart) in the search for her brother. The main suspect is notorious criminal The Panda ("The Prince of Blackmailers").
TV Guide called it a "routine second feature";[2] while Noirish wrote, "This is a very, very workaday comedy thriller, with most of the action being played as light entertainment and one character—the tiresomely misogynistic safecracker Nobby Knowles (Victor)—being played strictly for laughs".[3]
