Detective Mason is off duty for the night and drinking at a bar around closing time when he gets a call from his boss, Chief. Chief tells Mason to head down to the 'Nice and Easy' bar to investigate some alleged murders but this happens to be the bar at which he is drinking. Chief tells Mason that he is sending down his partner, Donna Bleshing, to help him out, but when a mysterious stranger claims to be his new partner, Mason is thrust into a world of lies, murmurs, and heavily encoded maps. It's up to Mason to solve the crime before morning or risk another disappearing.
