A disheveled Asian man approaches sex workers on the back streets of the French capital night after night. He isn’t after an assignation, but hunting for his wife, who vanished while they were on honeymoon two years earlier. As a lengthy flashback reveals, initially Sang-ho (Cho Jae-hyun) assumed she had been the victim of a kidnapping, but in retrospect he has come to wonder if his sexually voracious but emotionally distant bride may have joined the demi-monde of her own free will.
