After a prominent judge is injured during a struggle with some thugs demanding money from her in exchange for a strange tape, Bruce Wayne decides to take a trip to Yucca Springs, a resort where the judge had vacationed, and consult Dr. Hugo Strange, a psychiatrist. Bruce soon learns that Strange has invented a machine that extracts people’s darkest secrets from their minds and transfers them to videotape — and now Strange has proof of Bruce’s secret identity as Batman, and plans to auction it to three of Gotham’s prominent crime bosses.
