非婚不可A story of a police who infiltrates inside Yakuza which has business in US soil. But soon he discovers the beauty and respect of family he's offered place in.. Companela's guys, Italian mafiosos are seen arrogant and dumb, while Japanese criminals are somewhat peace loving; a bit too romantic setting. But still, not bad setting. Ryo Ishibashi acts well as Japanese Yakuza, and Viggo Mortensen is ever so cool.
