Magno, the Great Spanish superhero, vanished from public life after his implication in a child molestation scandal. 20 years have passed and now a documentary filmmaker follows the trail of the fallen hero to make a movie about him.

Magno, a superhero of extraordinary powers (he can fly, he is invulnerable, etc.), was repudiated years ago due to dubious accusations, and now works as a greengrocer. The film follows him closely day and night, while reviewing the back history of this character from his youth years (towards the 1930's) till today, uncovering little by little how he ended up in his current situation as a forgotten social pariah.
