José Garcia co-writes and stars in this French remake of the 2011 comedy 'Starbuck'. 40-something slacker Diego (Garcia) discovers that, having made money by donating his sperm to a clinic 20 years previously, he is now father to 533 people which has earned him the code name Fonzy. Angry at his behaviour, over 100 of his offspring have filed a class action against him. Meanwhile, Diego learns that his girlfriend Elsa (Audrey Fleurot) is pregnant but, doubting his commitment, has decided to bring the baby up on her own. He secretly discovers more about some of his children and begins to care about their lives but will he finally take responsibility for his actions?
