The Titans attempt to thwart the villain Cinderblock as he breaks into a prison to free a specific prisoner, but their lack of teamwork lets both get away. Cyborg and Robin start arguing over who is responsible, and Cyborg quits. Cinderblock turns over the prisoner to the mysterious "Slade," who when awakened, becomes Plasmus. The remaining Titans go after Plasmus, but are overwhelmed until Cyborg shows up and helps them defeat Plasmus after capturing Cinderblock, leaving Robin to wonder who is the mastermind behind the plan.
