It’s the 70s, and these three vets just got out of Vietnam after doing some crooked business there, and are on a boat headed home. But then two of them screw over the third guy, and throw him in the ocean! Luckily he survives, and gets washed up on an island where these Japanese World War 2 soldiers are holed up unaware that the war is over! And one of them teaches him “the art of the samurai”… The rest of the movie is the neo-samurai guy getting revenge on his former buddies.

It’s a pretty entertaining movie if your expectations are low and you’re in the mood for a campy but heartfelt action movie with a 70s feel. The ending is kinda sad tho.

Apparently it was originally released as “Death Force” but the opening title says “Vengeance is Mine” for some reason; looks like it was released on home video as “Fighting Mad”. From IMDB images I see it was “El Samurai Negro” in Spanish and “Deathforce” in Swedish!
