Half Japanese, v2

Joseph Gordon Levitt is the half-Japanese son of an aging Yakuza boss.

The film opens in Tokyo. An assassin takes someone out. It is unclear who the assassin is.

Cut to JGL in America. He runs one of his father's legit companies. Seems like a normal enough guy. He gets a call. It's time to come back to Japan. It was his half-brother (big shot in the Yakuza clan) who was assassinated.

JGL returns to Japan. We discover that he grew up there -- he is fluent in Japanese. His mother was one of the American girls brought over to work in one of his fathers sex joints. In a super cool reveal, we see JGL back in his Tokyo apartment. He takes off his suit and shirt and we see his FULL BODY TATTOO.

JGL's family is being assassinated one by one. His father doesn't know who is doing it. JGL and his half-brothers must HUNT THE ASSASSINS while being HUNTED THEMSELVES.

Alegiances are unclear. The brothers are all in competition to take over from their father. The father doesn't want to give up his position and has been undergoing surgery to unnaturally extend his life. The family's new gig -- human organs.

In the end, one of his brothers turned out to be involved with the assassins, and JGL's father is pretty diabolical (we'll work in him doing something bad to JGL's american family, or some backstory with JGL's mother).

JGL ends up on top, for himself and nobody else. One for one, and one for all.
