Agnes, a down-and-out waitress imbibing vodka and coke (in powdered form) in her dirty motel room, nervously awaits the return of her ex-con ex-husband, Jerry Goss, who she assumes is the source behind the barrage of silent phone calls. Her lesbian best friend and co-worker, R.C., brings over Peter, a passer-through she picked up at the bar. Polite, serious, and seemingly benign (“I’m not a serial killer,” he calmly repeats after overhearing Agnes joking with R.C.), Peter begins to break down the bitter wall behind which Agnes takes refuge. After platonically spending the night and witnessing Agnes’ black-eyed “reunion” with Jerry the next morning, Peter’s remarks and behavior start becoming darker and more paranoid—especially when he discovers that a certain Dr. Sweet has been asking questions about his whereabouts.
