Harry Lucas, an employee of the American Mint, accidentally broke 50,000 yuan, but there was not a shred of evidence to prove his innocence. So he asked Papergolis, a retired printer, and Avery Dugang, a skilled safe thief, to help steal the moulds. Du Gang, who lost his hearing for some reason in prison, got a hearing aid from Luther Burton, the pawnbroker, and Bolton planned to participate when he learned of their plan. Luther, the "manager" of the plot, recruited Rove in the sewer to help them get to Rove at the Mint and the operator of the "cruise boat" at the children's amusement park, the captain who could help everyone sail in the sewer, as well as ice cream vendors. It can be used as bait to attract the beautiful and good Vina. Finally, enough to embarrass all professional criminals, when Vina was successfully distracted on the day of the invasion, Harry's motley army full of money was able to escape with the 7 million yuan they had stolen!
