“Always lie. Never betray.” In order to keep his family free from financial worries, Marc Duval, a Frenchman expatriated to Gibraltar, becomes a spy for French customs. Working up from petty trafficking to moving shady cargo, he progressively wins the trust of Claudio Lanfredi, a powerful cocaine importer tied to the Columbian cartels. This in-depth immersion in the world of drug trafficking forces Marc to take increasingly serious risks. Permanently on a razor’s edge, only his lies still keep him alive.
