Fan Casting Last Hit

After a final hit, supposed to keep them safe forever, five experienced criminals, working regularly together for years, stop in the middle of the night for an isolated motel in the middle of nowhere for a while. However, they realize that strange things are happening around here, the place being almost exclusively frequented by people they know "professionally". Whatever is going on within its walls, it's obvious that someone doesn't want to let these criminals collect their pension... unless it's one of their own ?
