I have a grey market copy, full screen but small (does not fill the entire HD TV screen), good enough resolution, with English hardsubs. I'd buy a legitimate copy if available as it is worth the upgrade. The bad guy is established in the first scene by rape and murder. The authorities lack the power - martial arts power - to arrest him. Enter our hero, Polly Kwan. She goes straight to the brothel and captures him. Basically it is a hostage situation plot after that. Sometimes the actions are smart, sometimes the actions are not so smart. It all ends up in a glorious slaughter ending that Jimmy Wang Yu would have smiled at. The martial arts is overall good enough for 1972 but some of the wire work looks more like puppets than people. Overall, I liked it and rate it a solid just above average six for the year and genre.
