The Hard Way

Angoulême.

Some sort of retired Dirty Harry, 57-year-old Thierry Chevalier is back on duty to investigate a series of murders that bear the signature of Laporte (32), a killer he put behind bars... by extorting a confession from him... 

But what if Chevalier had imprisoned an innocent man? Placed under the orders of Cne Kabongo (32), as progressive as he is conservative, they will try to solve this mystery... That is, if they manage to put up with each other...
