UNSOLVED CRIMES

Nine years of lies. Nine years for the ice to give back its dead.
In 2015, the tragedy of the "Chalet of the Five" was officially closed. Jérôme Mercier, a carpenter who knew too much, was found dead of exposure in the snow. The following day, Inspector Éric Vasseur, the investigator assigned to the case, was found hanged. A convenient suicide, a case buried by the chain of command.
Today, Marcus Durand, a worn-down detective with the Cold Case Europe Division and Vasseur's former partner, refuses to let the past disappear. By reopening the file alongside Léa Santini, an unrelenting investigator from the National Financial Prosecutor's Office, Marcus uncovers something impossible: a hidden ledger linking the chalet tragedy to Arbor Group and the highest echelons of the criminal division.
But the institution does not allow itself to be judged. It adapts. It cleans. It grinds.
To silence the truth, the state machine turns against its own agents. From the cold stillness of crime scenes to the carpeted corridors of the Interior Ministry, Marcus and Santini become the targets of a merciless manhunt - one in which the state no longer hesitates to use its most extreme methods, going so far as to target Marcus's own daughter.
In a world where the law is nothing more than a weapon of mass destruction in the hands of those who control it, only one rule applies: the truth is paid for in blood.
A procedural noir of absolute darkness, in the finest tradition of Nordic Noir, where the worst enemy is not the criminal - but the system itself.
