Joanna and the Watsons are called in by the Whitechapel Playhouse to find Pretty Penny, a lovely, young actress who has gone missing without reason or notice. While on their search, the trio is asked by Scotland Yard to join in the hunt for a vicious murderer whose method resembles that of Jack the Ripper. It soon becomes clear that The Ripper has reemerged after a 28-year absence and is once again murdering young prostitutes in Whitechapel.
