aka The Last Reunion
In an overly long opening sequence in Japanese occupied Philippines during WWII, a young boy -played by a kid with limited acting ability - sees his parents killed and mother raped by US soldiers.
Thirty two years later, the son is a man who is looking for revenge. Conveniently the military unit is having a reunion. Their reunion mostly consists of drinking, brawling, dancing with women, and hanging out in discos with bad bands. And all of them hate their buddy Steadman, but to be fair, Steadman is an ass.
Leo Fong, who plays the adult son, buys a sword and says he's going to warn the men in obscure ways that he is going to kill them. What this really means is he tells them they are going to die right before he kills them.
Keep an eye out for the D'Hi Octave Band who look like the Philippino version of KC and the Sunshine Band, complete with white jumpsuits with sequined flames. They sing "Zodiac Lady" a song about all the zodiac signs. Oh yeah.
