Watch Cabaret (1986) Official Trailer

A young jazz musician's desire to advance in his career runs afoul of organized crime in this thriller from Haruki Kadokawa. After a saxophonist starts playing at a particular nightspot, a thug from the Yakuza adopts him as a special friend for no greater reason than he plays one of his favorite songs well. As the dangerous life of the gangster intertwines with that of the musician, it brings harm to the musician's girlfriend, who is raped. This changes the young saxophonist's attitude about his patron, but his Yakuza "friend" is still too embroiled in his own problems to worry about anything else.
