basically i only saw a scene of it but i remember it, so it was a french movie and there was a killer who got in an accident with a guy the killer had a Mercedes car if that can help im pretty sure or bmw, the killer wanted to pay the dude but he didn’t want to i think and called police, when a cop got there the cop wanted to check the trunk of the car so the killer killed both the cop and the man. If anyone could help i really want to watch it
