Joe Musashi has to stop a criminal organization called "Zeed" who are kidnapping the children of his ninja clan. Through five missions (consisting of three stages in the first mission and four stages each in the rest), Musashi must make his way to Zeed's headquarters and free all the hostages in the first two or three stages before confronting the boss at the final stage of each mission. At the start of each mission, the player is shown their objective, followed by a file containing a photograph of the enemy boss and a map display pinpointing the location of the next stage.
