During a spectacular break-in at the villa of film star Marion Milner, the jewel thieves fortunately only manage to get their hands on imitations of the valuable jewelry. The police suspect the notorious master thief Silver-Jim, whom they have long been after. The commotion surrounding the break-in comes in quite handy for film producer Otto Pitt, who is currently shooting a crime film, as he hopes it will generate some free publicity for his project.
