The film is a strange and anti-hero tranposition of a very popular animated manga cartoon in the 80's called Steel Jeeg. Here, a young outlaw (Enzo) is somehow affected by radioactive waste in the Tiber water in Rome. He subsequently finds out he has gained super power and interprets them as a reward for never having managed to enter the criminal world that counts. The inide joke reveals itself when Enzo meets Alessia, who believes the charming hero is the peronification of the hero in the cartoon she used to watch.
