John “Spider” Spiedel is a college dropout who is drafted into the war as a combat engineer. Scared, he tries to keep his head down and stay safe, a plan that works until the Tet Offensive, when he is wounded and sent stateside — and receives a devastating diagnosis. And while he’s been away fighting, his girlfriend, Beverly, has fallen in with the hippie movement in an attempt to rebel against the repressive values of American society and the injustice of the war that took her boyfriend overseas.
