In the 16th year of the Republic of China, Shen Yanqing, the daughter of a famous Huaiyang chef, was kidnapped by the cold-blooded warlord Lu Qingxiao and became his private chef. Outsiders only know her as an unfortunate bird in a cage, but they don't know that every delicacy she indulges in contains fatal information that can be delivered to the enemy camp. When the assassination order and the heartbeat come at the same time, at the last "unification of mountains and rivers" banquet, will the spoon in her hand scoop up poison or redemption? This is a life-and-death espionage game that uses the tip of the tongue as the battlefield and love as the bet.
