The Bogeyman (1953 film)

In order to guarantee the well-heeled participants' safety, numerous private detectives are hired as security.

Despite this massive protective presence, a clever gang of crooks who call themselves "The Night Ghost" manage to break into the hotel safe and steal considerable sums of money.

This now calls the bright maid Trixie into action, who loves to devour crime novels and was just waiting to finally experience an exciting adventure herself.

She is joined by up-and-coming author Conny Cooper who has already achieved some fame as a crime novelist.

The two track down the thieves and put the gang, including the somewhat dumb crooks Ladislaus and Gustav, under lock and key.
