Wei Xing, Zhao Yunsheng, Tang Ming, and Fang Xiaoyun grew up in an orphanage together.
One day, Wei Xing accidentally learned that his girlfriend Fang Xiaoyun was having an affair with his buddy Zhao Yunsheng. So Wei Xing carefully planned a car accident. However, a small omission left important clues for the investigation of the case.
As a policeman, Tang Ming couldn't believe that his friend Wei Xing was actually the murderer. In order to escape reality, he created the first world. Fang Xiaoyun, Zhao Yunsheng, and Wei Xing in the first world died when they were young. But when he just figured out the relationship between reality and the first world, he found that he had entered the second world where Fang Xiaoyun, Wei Xing, and Zhao Yunsheng were not dead, and he could not get out.
In order to return to the real world, Tang Ming planned a car accident, but he did not expect that he would also die accidentally. But things didn't end there.
When Tang Ming died, the dream woke up, and it was Wei Xing who woke up. It turns out that Wei Xing created this dream for a certain purpose. Now that he has woken up from the dream, Wei Xing has to face reality again. In reality, Tang Ming still held evidence that Wei Xing was the murderer, so Wei Xing decided to kill Tang Ming.
But Wei Xing didn't expect that Tang Ming actually had a hand.
At the same time, Tang Ming did not expect that at the moment of arrest, Wei Xing actually smiled and said to him...
Dreaming is just to escape from reality and seek temporary spiritual comfort.
So who is living in whose dream is not so important. Just live in a dream, isn't it?
