The fine line between drama and real life is crossed with tragic results in this German horror mystery film that is set in modern London and centers on a stage production of Jack the Ripper's life. During the run of the play, a series of murders, eerily similar to Jack's, occur. This doesn't bother the lead actor too much until he discovers that his fake knife has been replaced by a real one during a performance. Horrified, he flees the theater. Pursued by Scotland Yard, he must somehow prove his innocence lest he be sent to the gallows.
