This short shows the entrances of the various Hollywood studios, then specifically visits Warner Bros. / First National Studios. We start at the casting office, then see Busby Berkeley and choreographer Bobby Connolly working with chorus girls on production numbers. Then come some candid shots of several contract stars. Finally we see comedian Hugh Herbert filming a scene for an upcoming release, then the various behind the scenes steps that transition the raw film in the camera into the finished product.

In a spooky hotel on the coast of France, two bands of crooks are working independently of the other in an attempt to steal the inherited fortune of an American girl, Sue Tally. Along the way the heiress is kidnapped, three murders are committed, a girl appears in two places at once, mysterious persons roam about the old hotel at night and mysteriously disappear, and there is a hidden room without any doors.
