A documentary about the creation of comics series "Largo Winch".

Jules, a young Parisian postman, secretly records a concert performance given by the opera singer Cynthia Hawkins, whom he idolises. The following day, Jules runs into a woman who is being pursued by armed thugs. Before she is killed, the woman slips an audio cassette into his mail bag...

After a powerful billionaire is murdered, his secret adoptive son must race to prove his legitimacy, find his father's killers and stop them from taking over his financial empire.

Largo Winch, devastated by the kidnapping of his son, realizes that if he finds those responsible for his bankruptcy, maybe he'll see his son again.

A murder is committed in the building where Aurélia Maudru, inspector of the judicial police in charge of the investigation, lives.

In rural Westphalia, Franz Berger struggles to keep his inn open. On this day, a bluff, overbearing bully, Hermann Walzer, has booked the dining room for a wedding banquet for his son Mark. There's bad blood between Berger and Walzer, so when the first course, shrimp cocktail, is off, Hermann storms out with the wedding party vowing not to pay. Franz locks the loo door, taking prisoners of the bride and Hermann's wife while he also locks the estate's outer gates, leaving Hermann and the rest outside. Walzer, a pheasant hunter, lays siege; shotguns, rifles, grenades, a shovel, and other weapons leave no one safe. Will it take death to bring these men to their senses?

Propelled to the head of the W Group after the death of his adoptive father, Largo Winch decides, to everyone's surprise, to sell it, and use the proceeds to create an ambitious humanitarian foundation. But on the very same day, he finds himself accused of crimes against humanity by a mysterious witness. To prove his innocence, Largo will have to retrace the steps of his past life, in the heart of the Burmese jungle.
