Number 6 in the series of Girl Boss movies, this and the last one are directed by Ikuo Sekimoto. Again in this installment, we get a lot of the traditional Girl Boss flavor: Prison fights, revenge, Yakuza involvement, nudity...just not a lot of anything new to it.

Unless you want to count cooking stray dogs to sell the meat or peeing. 
Hmm...

Anyway, bad girl Keiko (Reiko Ike) stabs the man who killed her sister and goes to jail, where she's constantly beaten up and intimidated by Girl Boss Miwa (Ritsuko Fujiyami). Once Miwa's released, Reiko works her way to the Boss spot of the prison, and is released one year later (at the end of the opening credits).

She's thinking revenge.

Helping some friends with their debts to a club, she finds out its run by Oshima (the always snarling Toru Abe), the man she stabbed and went to prison for. Regular Sukeban actress Ryoko Ema is another Girl Boss she squares off with and Tsunehiko Watase plays a cool yakuza.

There are what I guess you'd call plot twists, to keep you on your toes; let's just say it's a fun little romp that has Reiko in it, with lots of cool fashion, some great music (a few of the songs are on the Miki Sugimoto vs Reiko Ike CD), and an entertaining finale.
