When Bruce Lee died in 1973, Hong Kong film moguls were desperate for someone or something to fill the massive martial arts movie gap, which Westerners were demanding. The solution was, to use Bruce Lee look-a-likes, and have the same titles that had been box office smash hits for Bruce Lee. This movie is a perfect example, using Dragon Lee who is more of a look-a-like for Jason Scott Lee (Dragon: The Bruce Lee Story) than Bruce Lee, and the title Big Boss 2, but has nothing in common with the original Big Boss. Having said this, it is a great action movie on it's own, this Kung fu thriller is set in the time when the Chinese were being oppressed by the Japanese, and the main threat is from a big Japanese gang boss (Bolo Yeung), who is trying to stop and kill any Chinese renegades and their secret society. Messages have to be sent between groups, and Lee Han San (Dragon Lee), the son of Lee Wan Jan, is a trusted messenger as his father was a leader of the cause. When trying to deliver a message, he is shot by the Japanese big boss, but luckily escapes and is found and saved by his father's old friend, Jo Chu Chee. Here Jo, his wife and his daughter, Wan Ner, help Lee Han San to a full recovery. Whilst Lee is convalescing, the big boss sets his men the task to track him down and kill all who have anything to do with the renegades, including Lee and Jo. The battle begins for Lee to stay alive and keep his father's legacy alive. But at what cost.
