Trained Marine sniper Nathan McBride is no stranger to sacrifice. Fourteen years ago, he paid a heavy price in service to his country when he was tortured to the brink of death by Nicaraguan interrogator Montez de Oca. When the FBI uncovers a mutilated corpse from a remote Utah lake, McBride must face the ugly truth that Montez de Oca is back in action and will continue to kill unless McBride can stop him.

When a mysterious note referencing a top-secret U.S. operation is tossed over the wall of the embassy in Nicaragua, Nathan McBride and his old friend Harv are pulled out of retirement by the CIA and sent to investigate the situation. After all, Nathan has a history with the place--but last time he was there he barely made it out alive.
