Early in the episode, Marcel is found dead, with a slit across his throat. At first everyone thinks that another inmate, Dédé, is the one who killed him. However Commissaire Swan Laurence arrives on the scene. He notes that Marcel had been killen by someone left-handed whereas Dédé is right-handed. Laurence asks who is left-handed and everyone turns to look at another inmate Damien.
