The talented chef Zhou Chen, who was abandoned by the mainstream, uses ancient ancestral methods to cook a secret soup that can awaken memories in an abandoned back kitchen, but never opens it to outsiders. In order to redeem his conscience, the down-and-out director Su Yan sneaked into the abandoned area to track down the legendary "crying soup", but accidentally uncovered the bloody truth behind Zhou Chen's silence. When Michelin judges, food giants, and former apprentices appear one after another, a bowl of soup affects three serious crimes and redemption. Su Yan's camera is not focused on delicious food, but the fragments of human nature; what is boiling in Zhou Chen's pot is not soup, but body heat forgotten by the times.
