A redux of the classic and long running Zatoichi franchise, Ichi is a blind musician who happens to have incredible sword fighting skills. In her quest to find the man who brought her up, she encounters numerous swindlers, villains, and gangsters who try to take advantage of her disability, but she fights back using the sword hidden inside her walking stick. Some time into her journey, she meets Toma, a cowardly samurai who Ichi ends up saving from the ruthless Banki gang. The pair unwittingly become entangled in a turf war between two factions vying for control of a pivotal village, while Ichi learns that the outcome of the conflict might determine if she will find the man she is looking for.
