The plot opens with the hero (Tsuruta) leaving prison, having served time through taking the blame for a fellow gang member’s crime. However, his former gang boss seems to have gone to seed, with people now killing each other and dealing in drugs. The hero then teams up with a lone operator (Tamba) who specialises in shaking down gangsters.
It’s been five years since her husband had passed away. Fuyuko lives in the quiet suburbs, in a small but loving home with her three beautiful daughters. Haruko, the eldest, is the lead vocalist in a band. Natsuko is the conscientious type, who spends her days in ballet classes beautifying herself. The youngest of the three, Akiko is a bookworm who found her niche in philosophy. Although the sisters may appear to have nothing in common, there is one thing they all agree on; "Mom needs a new husband".
