Description：On this day, a shocking treasure theft occurred in the city, and the mastermind behind the scenes turned out to be a group of nonsensical thieves. In order to avoid being discovered, they hid the stolen gems in a teddy bear. Unexpectedly, the "expensive" bear was sent to the toy factory by mistake, mixed in with thousands of identical teddy bears. The thieves were very upset. It would be like looking for a needle in a haystack to find it. At this time, the toy factory owner (played by Kwan Lee-kit) exchanged souls with his son. The son (played by Zhang Yijie) suddenly became the boss, and the father went to school with a schoolbag on his back. At a moment of chance, the father and son encountered a jewel thief, and the "son" was hijacked and held hostage by the thieves. This made the seemingly cowardly "dad" very anxious. But how can the "dad", who is only ten years old, rescue the one in danger?
