Simon (2014)

Justin is invited to a seemingly ordinary office party for a work colleague, Simon. Simon isn't exactly someone Justin knows by sight. Or sound. Or at all. OK, he has no idea who this guy is, he's just going to grab a free beer and hit the road until Simon sees Justin. Then Justin sees Simon's dazzling fiancee, Rebecca. And then things really start to spin out of control - you won't believe the result!
