I only caught the last bit of it, and not sure which bits you havent seen. but heres what I saw
So a man is missing (he was convicted of rape of a Japanese girl?)
He had previously went back to see his ex-girlfriend / wife to tell her he was innocent of the rape, and he had proof. She didnt want to know, she had remarried, and was happy...she also has a little boy, which he is the father of, but was unaware she had given birth
They think her new husband is responsible for the dissapearance, as he threatened him (in writing and with a gun) He says he is innocent, and that he even got a call from the local police saying the guy has been picked up on a drunk charge.
That call turns out to be fake, they trace it back to a garage, where an old friend of the missing person works. This guy was a marine, and was also in Tokyo the same time the rape took place....which is why he wants the tape that proves the other guy is innocent, as it would prove him guilty. As the guy walks off, the garage owner wallops him with a wrench, and we next see him, being found in a barrel full of tar or something.
He confesses what happened, and so avoids going to a Japanese jail, and meeting the Yakuza
The mother of the missing person, (now deceased) is told she has a grandson, and that he was innocent of the rape.
And thats about it.
