Bruce Lee's breakthrough Hong Kong film may be a bit rough around the edges, but it remains an electrifying example of the martial arts master at work. The plot is fairly perfunctory: Lee plays a young man who travels to Thailand, promising to keep out of trouble, only to find himself caught up with a drugs ring. However, Lee's graceful charisma shines throughout, and director Lo Wei and fight co-ordinator Han Ying-chieh (who also plays the villain of the piece) orchestrate some stunning set pieces, most notably a fight in an ice factory. You may know this film better under its two other release titles, Fists of Fury and Tang Shan Da Xiong.

Cheng is a young Chinese mainlander who moves in with his expatriate cousins to work at an ice factory in Thailand. He does this with a family promise never to get involved in any fights. However, when members of his family begin disappearing after meeting the management of the factory, the resulting mystery and pressures force him to break that vow and take on the villainy of the Big Boss.
