When the digital-mad Benjamin turns 18, he inherits a box of ancient artefacts from his missing father. He gives an antique book to Slien, a girl he has his eye on, and unintentionally sets off a chain reaction. An old man called Zeppos is also very interested in the book, which once belonged to the cartographer Mercator. Using the secret messages in Mercator's book, the trio uncover a mystery, while having to stay one step ahead of a shadowy rival.

On the streets of Antwerp, Badia, Junes and Volt are trying to tear themselves away from their past, but the underworld is inexorably pulling them back in.

His friends have to make a choice: stay loyal to Adamo or choose safety.
