Synopsis:
Wonder Woman attends the magic show of Mystik, a master magician. A rival magician named Tricco seeks to expose Mystik's tricks and uses Wonder Woman's lasso to do so. Mystik becomes angry and wants to kill Tricco. So does his assistant Oriel and another magician Slydine. Wonder Woman and Mystik's nephew Darcy Wells are finally able to restore the peace.

Wonder Woman then offers to perform a trick for the crowd. While she performs, someone secretly binds her legs with her own magic lasso. The other magicians then convene backstage in Room B. After a gunshot is heard, Mystik, Oriel, and Slydine emerge from Room B with Tricco's dead body inside. All three claim to be innocent of his murder.

Steve Trevor and Wonder Woman investigate. They discover that while Darcy came out of Room C, rooms A, B, and C are all set to slide back and forth. Therefore he was also in the room when Tricco was killed. When the trick is exposed, Darcy is caught for the murder that he intended to use to frame his uncle.
