Da Lei and his former cellmates plan to steal 1.5 million dollars worth of ancient gold coins. The original flawless plan was about to change, because Timmy, the 11-year-old son whom Da Lei had not seen for a long time, was suddenly sent home by his aunt, making the three old thugs at a loss and at a loss as to what to do. The next day, they still decided to proceed as planned, and successfully robbed the gold coins and took them home to hide. But their strange behavior was seen through by the shrewd Timmy, who secretly hid the gold coins somewhere else, as a condition, asking his father Da Lei to accompany him for a week and let him enjoy the father-son affection he had never had before. Big Lei and other three reluctantly agreed and watched each other closely for fear of being hacked.
