Matthew Thorne, a former doctor, must perform a delicate surgery on his brother, crime boss Rupert Thorne, but cannot do it alone so he kidnaps his former colleague, Dr. Leslie Thompkins. Batman rushes to save Dr. Thompkins before Rupert's men kill her.
- Back-Alley Doctor: Matthew Thorne. He lost his license when he pulled a bullet out of his brother, notorious crime boss Rupert Thorne, and never told anybody. He was relegated to a licenseless, back alley existence afterwards.
- Freeze-Frame Bonus: The closest thing we get to a definitive date for the series is Leslie Thompkins's yearbook, which identifies Matt Thorne's graduating class as 1901.
- Tell Me About My Father: At the end of the episode, Bruce bails Matthew out, and the doctor is instantly suspicious about his motives — until Bruce says this trope's name (the doctor had been good friends with Dr. Thomas Wayne in medical school). The episode ends with Matthew reminiscing and an enthralled Bruce looking on.
