Sam (Harrington) surprises his group of old NYU college friends when he shows up at a wedding in Athens, GA. He hasn't been seen or heard from in years -- traveling the world alone since Amy (Robertson), who is now married, left him. Sam's unexpected arrival threatens to unravel her comfortable world. The once tight-knit group is fractured, having drifted apart after graduation. Will the weekend be a disaster when old conflicts and love affairs spark anew? Not Since You is a funny, romantic drama featuring a vibrant cast that was made much in the same spirit as the generational classic, The Big Chill.
