Lin Xiaohe, a first-year high school student, was hit by a car.
After waking up, he found himself floating in mid-air - his body was occupied by a man named Lu Zheng.
Lu Zheng was an agent who was betrayed by his teacher and died in the mission. His soul accidentally entered Lin Xiaohe's body. He is cold, pragmatic and knows it all. Lin Xiaohe is cowardly and introverted, but extremely perceptive. No detail can escape his eyes.
Lu Zheng wants to find out who betrayed him. Lin Xiaohe just wanted to get his body back.
The two share a body and are forced to cooperate. Lu Zheng was in charge of fighting, and Lin Xiaohe was in charge of complaining. One wants to find out the truth, and the other wants to survive.
But they soon discovered that the car accident was not an accident, but a murder. The murderer's target has been Lu Zheng from the beginning.
What's even more troublesome is that Lu Zheng's girlfriend is also investigating the case...
