But there are a couple of other guys looking for the book, quite why isn't explained. Bruce's sister (Yuan Man Tzu) is being forced to become a prostitute, scared into submission by seeing a woman tortured with a lizard. Thankfully Bruce saves her before she has to sell herself and he takes her to his friend Mina (Nora Miao) to look after. Not that Mina does a very good job as she and Bruce's sister are captured by the bad guys twice...
The other guys looking for the book turn out to be a cop (Michael Chan) and his new friend (Nik Cheung). All explained in the end then. After much muddled plotting, and random scenes, and lots of fighting (of course) the Bruce Lee book is discovered and Bruce learns finger kung fu. Unfortunately Lee Hung also gets the book and this sets the scene for a final gruesome showdown...
A clumsy film that contains a few too many strange awkward scenes (including a bizarre scene where the bad guys set a ring of gasoline on fire and begin to molest some unfortunate women in the centre of the fast approaching flames) though mid-1970s HK looks very groovy. Not a film for plot, a film for kung fu action which often is pretty decent.
