After the Northern Garrison Army returns victorious, the military kitchen prepares meat porridge to celebrate the victory and reward the entire army. Zhao Heng, a military cook with a kind heart, secretly gives Chen Xiaoliu, who has been wounded in battle, an extra serving of thick porridge. The two joke and laugh together, and the military camp is filled with cheer and laughter. But disaster strikes in an instant. Soldiers who have just eaten the porridge begin collapsing one after another from poisoning. Chen Xiaoliu is the first to clutch his throat, convulse, and fall unconscious in agony. The laughter instantly turns into horrific screams. Zhao Heng rushes to Chen Xiaoliu's side to examine him. When he notices the millet grains Chen Xiaoliu has vomited, he suddenly realizes that someone has poisoned the porridge. Three hundred bowls of celebratory military porridge are secretly laced with deadly poison, plunging the entire military camp into a grave crisis.
