Who Wants to Be a Superhero? - Episode 3

Sam Nixon and Mark Rhodes continue their search to find the world's next great superhero. The Superheroes set off to meet Sam and Mark for their next mission on the roof of a warehouse in east London. But sinister forces are at work leaving the Superheroes trapped on the roof opposite. With no other means of escape, the heroes face only one option - crossing a plank between the two buildings, 18 metres high. Who will remain calm under pressure, and more importantly, who will have the inner strength to conquer their fears? Back at the lair, the Superheroes are asked to put themselves in order of who they think behaved in the most superhero-like way. Will they choose an order agreed by all, or could this cause the first disagreement amongst the group? Plus, Sam and Mark call three Superheroes forward to face the Power Down. But who will become the first Superhero to return to their secret identity and leave the lair for good?
