Triple bill of martial arts action starring Sonny Chiba as mercenary karate master Takuma 'Terry' Tsurugi.

In 'The Street Fighter' (1974) gangsters seek to hire Tsurugi to kidnap Sarai (Yutaka Nakajima), a wealthy heiress, but when he learns the yakuza are behind the plot, he refuses. They vow to kill him and Tsurugi swears to protect Sarai and exact retribution on all who come after him.

'The Return of the Street Fighter' (1975) sees Tsurugi hired to kill two informants, but when he realises one of them is his old friend Kendo Masaoka (Masafumi Suzuki), he goes on the run.

Finally, in 'The Street Fighter's Last Revenge' (1979) Tsurugi finds himself involved in a case of government corruption and is soon out for revenge after being double-crossed by his latest clients.
