One day, Shao Yu had a dream where his wife was intimate with a man who had his back to him. When he woke up and called his wife, he heard strange noises, which made him suspicious of her.

In order to find out the truth, he repeatedly followed his wife to catch her, but failed each time. The adulterer called and lured Shao Yu to a place in the S Club, where he saw a woman who was exactly the same as his wife.
