When Joe Valachi has a price put on his head by Don Vito Genovese, he must take desperate steps to protect himself while in prison. An unsuccessful attempt to slit his throat puts him over the edge to break the sacred code of silence.

Mountain Rivera is a veteran heavyweight and near-champion who suddenly finds himself washed up in the only trade he knows—prizefighting. Yet, threatened by gangsters for welshing on a gambling debt, Mountain’s opportunistic manager, Maish Rennick, schemes to get the ex-boxer into a phony wrestling match to make some quick money. Although he and his loyal trainer, Army, oppose the degrading proposition, the disillusioned Mountain begins to wonder if he has any options left.
