Valencia, 1993. Ignacio Jordá is an unguided missile: a young man who lives only for friends, parties... and sex, his greatest obsession. But Nacho is tired of being the black sheep of his family and wants to prove that he can do more. In his search for meaning, everything changes when he meets a fascinating woman, Sara Bernal. Thanks to her, he discovers that his talent is closer than he thinks: it measures 25 cm and is located in his crotch. The time has come to leave his mark on life... even if that means he has to 'fuck' the world.
