A quick trip to the capital goes horribly wrong when Blotto and Twinks get accidentally involved in London's criminal underworld ... It starts innocently enough at the intimate review 'absolutely everyone is talking about', Light and Frothy, where its glamorous star, Frou Frou Gavotte, has rather taken the fancy of Blotto's school friend Giles 'Whiffler' Trumpington. But while Blotto and Whiffler wait for the star outside the theatre to take her to dinner, Whiffler is seized and manhandled into the back of a cab which then drives off into the night ... Leaving Blotto with the problem of how to rescue his kidnapped schoolmate. Naturally, he enlists Twinks's help and the two of them encounter actors, singers, impresarios, revue writers, cockney showgirls and Scotland Yard's finest - and white slave traders, who succeed in abducting Twinks - leaving it up to Blotto and his trusty chauffeur, Corky Froggett, to rescue her before she's shipped off to foreign parts forever ...
