As a policeman, Ah Hua wakes up one day and becomes A Biao, a robber who robs a jewelry store, and stays with the robbers A Fei and Huang Mao. He hopes to bring criminals to justice, but at the same time he also hopes not to be arrested in this capacity, so he falls into a contradiction. He tried various methods without success. On the other hand, the robber A Biao crossed over to assume the identity of Ah Hua, lived with Ah Hua's family, and worked as a police officer. Both of them tried their best to pretend to be their own identities, and despite all kinds of strange behaviors that were inconsistent with themselves, they were all excused. While escaping with the robbers, Ah Hua kept informing the police of his location, but was evaded by the cunning Ah Fei for various reasons. A Biao felt the warmth in his life with A Hua's family and had the idea of occupying him forever. In the final arrest, Ahua killed the robber Huang Mao. The robber A Fei was shocked. He told A Fei the truth and persuaded A Fei to surrender. However, A Biao rushed over. A Biao and A Hua were shocked when they saw each other. But A Biao shot A Hua first. Ah Fei questions Ah Biao about what Ah Hua said. A Biao admitted in person but shot A Fei to death. Just when A Biao was about to shoot A Hua, he was shot by A Hua. Ah Hua, who was in Ah Biao's body, was seriously injured and died, while A Biao, who was in Ah Hua's body, became a vegetative state. Ahua's wife accompanies her husband every day and talks to him. Ahua finally returned to his body and woke up in the hospital bed.
