This early '70s effort from veteran exploitation director Greydon Clark attempts to create a more socially conscious variation on the blaxploitation genre, but devotes most of its time to thrills of the most lurid variety. The story begins with Jim (director and co-writer Clark), a liberal-minded white Vietnam vet witnessing the death of a black soldier. He returns home and attempts to deliver the fallen soldier's posthumous Purple Heart to the soldier's family. In the process, he angers Makimba(Tom) (Tom Johnigarn), an angry militant who was the soldier's brother. Jim and Makimba's paths continue to cross as the two deal with their problems: Jim struggles to decide whether he should settle down with the prim and proper Nancy (Jacqueline Cole) or live with the free-spirited Bobbie, and Makimba develops an ever-growing anger towards white society as he is hounded by racist white cops, Lt. Stans (Aldo Ray) and Sgt. Berry (Jock Mahoney). Tom is finally driven over the brink and takes action, resulting in a tragedy that changes both men's lives forever. Despite the serious nature of the story line, the film that resulted is an exploitative affair that takes every opportunity to titillate the audience with plenty of sex and violence. As a result, its attempts at social consciousness went ignored, but its salacious moments went over well with the drive-in crowd. Director Greydon Clark later revisited the blaxploitation genre with the even more exploitative Black Shampoo.
