An orphan, ugly, was adopted and treated well by the hero's mother when he was a child. After she died of illness, her heroic mother wandered the streets. Chen Lin's father found out that he was mistaken for a hero mother and his own son. One Christmas, the rascal was so hungry that he couldn't rob the hamburger in the hamburger shop. He Xiaomei, who was working in a hamburger shop at that time, helped him (so the rascal regarded her as a goddess). Later, he was arrested by someone sent by Chen Lin's father and sent to South Korea for plastic surgery, new identity, luxury sports car and admission notice to the police academy. When the rascal became a policeman, he provided clues to solve the case. Later, Chen Lin's father discovered that heroes are his own children, and hooligans are actually nothing.
