Late in the 1500s, an aging tea master teaches the way of tea to a headstrong Shogun. Through force of will and courageous fighting, Hideyoshi becomes Japan’s most powerful warlord, unifying the country.

Furuta Oribe is ordered to become tea master under Toyotomi Hideyoshi after his teacher Sen no Rikyū, the former tea master, was ordered to commit suicide. Princess Goh, daughter of the lord but adopted by Hideyoshi, is outraged when Rikyū's severed head is thrown in the Nijo River. She sends Usu, Oribe's servant, to retrieve the head and deliver it to Rikyū's adopted daughter.
