Leo is a young boy, aged 11, who lives in New York City. Life is no fun for him, as he was hospitalized because of an illness. Fortunately, the illness has unexpectedly given him an extraordinary power: the power to split to hover and fly in the air in intangible form, invisible and impalpable, while his physical body remains mostly asleep. In this form, he can go anywhere and even through walls. Meanwhile, Alex, a policeman, is hospitalized in the same hospital after breaking a leg in an accident. That was not helpful at all, because he was on the track of a bandit nicknamed "the man with the broken face", who had caused the accident and plans to take control of the city with the help of a computer virus in the next 24 hours. Leo and Alex will then join forces to save the city, all in less than a day.
