In Boston, the United States, the three artifacts that can enter the different-dimensional unsealed octagonal serpent are on display. CIA agent Mai Shiranui (Li Meiqi) is probing the secrets of the three artifacts from Iori Yagami (Li Weiyin), a descendant of the eight gods family. Unexpectedly, Lukar snatched the three artifacts into the pavilion and hid them into the different dimensions. Qianhe (Ye Fanghua), a descendant of the Shenle family, reveals that the grass pheasant sword that was taken is fake and entrusts Mai Shiranui to ask the Cao childish family for help. After snatching the artifact, Lukar lured the fighters of the KOF contest into a different dimension, intending to become the king of boxing. At the same time, in order to stop Lukar's plan, Mai Shiranui and Iori Yagami asked Cao Zhi, the heir of Caozhi's family, to fight together. In order to investigate this crime in the different dimension, the CIA also sent agent Terry to enter the different dimension together with Mai Shiranui and others. This film is based on the classic game of the same name.
