John Wick

You're a former mercenary named John Wick, nicknamed Baba Yaga. You retired five years ago. But at a gas station, you bumped into a gang of guys. You ignored them, but when you returned home four hours later, they break into your house and beat you up. One of them takes off his mask. You see his face and learn that he's the son of a mafia boss you used to work for. You pass out. When you come to, you see your dead dog, the one your wife gave you before she died. You become enraged. You go to the basement with a sledgehammer, break the floor, and take out the briefcase. You open it and take clothes, a gun, and gold coins from there. You get dressed and get into the car. Your wife's peace and you drive off to get revenge.
