Plot
The Doctor, Ryan, Yaz and Graham go back in time to Chicago to find the famous Harry Houdini and his troupe a few moments after Houdini and the Twelfth Doctor had a confrontation with a dangerous alien responsible for the murders of other Magicians in the area. The troupe band together with the fam to help protect a ring owned by Mr. Houdini that is actually a controlling device for one of the stagehands in his trope, Billy. The Doctor discovers that Billy is actually the dangerous, shape-shifting alien seeking revenge on his previous owners who forced him into slavery for the sake of their magic acts, Houdini included. The team manages to convince Billy not to kill Houdini and help him repair the ship in which he came to Earth in so he may leave again. As part of Houdini's act was to use Billy to make himself appear in two places at once, Billy switches places with Houdini and instead stays on Earth with Houdini's wife while the real Houdini flies away into space.
