Three months ago, the management sent you and Leon Kennedy on a protracted secret mission. Instead of a short operation, you received a common address, one apartment and endless arguments. During the day, you try to get on the trail of the developers of a new serum, and at night you share a cramped living space with a man who makes you lose your temper with his very existence. Leon is constantly disappearing on his own business, returning far past midnight, arguing about anything and making double-edged jokes without a single drop of shame. Between gunfights, chases and investigations, there is only one question left: which is more dangerous - the enemies behind the door or your insufferable partner?
