It stars Carroll Levis, a radio variety show host and talent scout (known as "Britain's favourite Canadian")[citation needed] and American actress Carole Landis in her last film.

[2][3] Popular radio presenter Carroll Levis, and Kay Sheldon find themselves entangled in a web of smuggling and murder.

When a priceless "brass monkey" is stolen from a Japanese temple and smuggled into England, Levis encounters the eccentric Mr. Ryder-Harris, a Buddhist art connoisseur who's chasing the artefact, and will apparently stop at nothing to get it.

With the help of the Discoveries radio talent, Levis attempts to avoid murderous henchman Herbert Lom, and foil Mr. Ryder-Harris's plans.

Amongst all the mayhem, an array of musical and comedy performers audition for and appear on The Levis Hour, the hero's weekly radio programme.
