Sam Nixon and Mark Rhodes continue their search to find the world's next great superhero. The Superheroes embark on their first crime-fighting mission, helping a VIP damsel in distress, Dani Harmer aka Tracy Beaker. Dani's hotel room has been broken into and some of her personal belongings have gone missing. She enlists the Superheroes' help to gather clues and find out who has done it. Will they prove their detective skills and help poor Dani or will they be too starstruck to solve the crime? Back at the lair, Sam and Mark round up some potential suspects from the hotel. The Superheroes come face-to-face with the prime suspects and study the line-up. But can they correctly identify who was at the scene of the crime? And more importantly, who was not? The Superheroes face another Power Down where one more hero will return back to their secret identity and leave the lair for good. Plus, Stan Lee makes a shocking announcement.
