The Banquet has been described as a loose adaptation(节选)of "Hamlet", featuring royal conflicts(冲突) and revenge(复仇)which is set in 10th century China. The new Emperor (Ge You) has usurped(篡夺) the throne(帝位)by murdering the previous Emperor. He marries the Empress (Zhang Ziyi), wife of the previous Emperor and stepmother to the Crown Prince (Daniel Wu).

At first, the Empress seeks only to protect herself, but as the new Emperor grows suspicious(疑心) of all those around him, she realizes that only by helping the Crown Prince kill him can she hope to survive. Together with the Chief Minister (Ma Jingwu),she tries to carry out this plot, but when the Prince is destroyed by hesitation, she thinks out a new plan and seeks the throne for herself. As the plot move towards its climax(高潮), the Emperor calls for a plentiful royal banquet, where each will seek the end of their enemies.

The Banquet differs from Hamlet in that it does not focus on the prince, but examines the feelings of each character. According to director Feng Xiaogang: "If Hamlet is about a prince who must make a choice involving life and death, then The Banquet is about how each character must face a choice of life or death... All are motivated by desire, but as soon as they have begun their plans must grow more extreme, and they move step-by-step towards the abyss(深渊)... They do not intend evil, but turn to it out of self-preservation and ever-growing ambition(野心)."
