Set firmly and clearly in the milieu of 2016, “Happy Ending” is the two-character story of a simple, benign and quite professional massage therapist who never knows who the next client might be. A dance of emotions and a tennis game of conflicting signals occurs when a new client walks in the door, full of hidden agendas and forbidden topics. Decorum is the standard and rules are rules, but rules are also made to be broken, unless you’re a cop. You’re not a cop, are you? Be honest. Or, perhaps most importantly, who’s really being truthful here? Note: full male nudity involved.
