Have you ever fantasized about being able to switch between multiple identities and start a new life at any time? In fact, Alice has been doing this for 15 years. However, at a party, Tom, her ex-boyfriend when she was "Jenny", recognized her. Tom was convinced that there was a history between them, but Alice just left in a hurry and refused to recognize each other. Tom wants to know what happened ten years ago and why Alice had so much experience. At Tom's insistence, the two finally opened their hearts and talked for a long time all night. "complete strangeness" depicts the life trajectory of two kinds of people and explores the multifaceted personality through a large number of sensory close-ups.
