Luke is a comic-obsessed eleven-year-old who misses out on the moment of a lifetime – thanks to an ill-timed toilet break. While he’s gone, an alien gives his clueless older brother Zack superpowers and a mission to save the universe. It should’ve been Luke! But when Zack is kidnapped by a villain with world-ending plans, it’s up to Luke and his friends to rescue him and save the planet – all without any powers of their own.
