In the closing days of the Vietnam War, a young Special Forces recon team leader, Sergeant Jack McCoy, is sent on a secret mission into Laos. Jack's team is ambushed by the NVA before reaching its target and he, his best friend, Charlie Mills, and a Montagnard team member are captured. The leader of the enemy unit is a Russian Spetsnaz officer who, in a fit of rage, kills a defiant Charlie in cold blood using Jack's own knife. Jack eventually escapes his captors and vows to one day avenge the death of his friend. Thirty-five years later Jack is the commander of a Sheriff's Department SWAT team in Las Vegas, Nevada. On a VIP protection detail at a Las Vegas hotel, Jack encounters the former Spetsnaz officer, now a diplomat and spy for the Russians. After a violent confrontation, Jack threatens to reveal the man's murderous act in Laos. A high-level CIA official intervenes, claiming the Russian is a valuable Agency asset. Jack cannot be dissuaded, so the official and the diplomat go after him with hired assassins and the streets of Las Vegas run red with blood. After two failed attempts on his life, Jack, now reunited with his Montagnard teammate and assisted by two friends, both Special ops veterans, lures his enemies to a remote ranch in Colorado. In the bloody showdown that follows, Jack learns why they are trying to kill him and why his team was ambushed in Vietnam. In the process he keeps a decades old promise to a friend and learns the true meaning of honor, loyalty, and friendship.
