Nomi Kanjuro is a samurai on the run after throwing away his sword for good. With him is his headstrong 9-year-old daughter Tae. A bounty is soon placed on Nomi Kanjuro and 3 assassins go after him. When Nomi Kanjuro is captured and placed in front of the local feudal lord, he is given a choice: a boy prince has been grieving ever since the death of his mother. Nobody has been able to make the boy smile. Nomi can attempt to make the boy smile within 30 days or he must commit seppuku (suicide).
