Sam and Mark continue their search to find the world's next great superhero. Nine superheroes remain in the lair. The superheroes discover that their secret identity files have been stolen from the control room safe. However, a discarded note reveals that one of Dr Dark's henchmen has taken the files and plans to hand them over at a cafe nearby. There is only one thing the superheroes can do: get into disguise and retrieve their files before they fall into the evil clutches of Dr Dark. At the cafe, the superheroes are working in pairs: one superhero has to distract the henchman whilst the other attempts to steal the files back without being spotted. This is the first time the superheroes have come face to face with one of Dr Dark's giant henchmen. So who will remain calm under pressure? How will they adapt if things do not go to plan? Who will successfully retrieve their files? Who will raise suspicion? And most importantly, will any of them be identified as superheroes? Plus, three superheroes are called forward to face the power down and one will be chosen to return back to their secret identity and leave the lair for good.
