(November 2015) Nick Parker (Rutger Hauer), an American soldier serving in the Vietnam War, is blinded by a mortar explosion, and soon after rescued by local villagers, who help him recover his health. Although he remains blind, as a part of his recovery, he is taught by the local master to be an expert swordsman, and to train his other senses. Years later, having returned to the United States, he visits old army-buddy Frank Deveraux (Terry O'Quinn), only to find that Deveraux is missing. Parker then rescues Frank's son Billy (Brandon Call) from an attack in which Billy's mother (Meg Foster) is shot and killed by the henchmen of Frank's evil boss, MacCready (Noble Willingham). These men apparently want to kidnap Billy in order to use him as leverage over Frank. Parker and Billy, chased by MacCready's men and lead villain (Randall "Tex" Cobb), make their way to Reno, Nevada, where Deveraux is being forced to make designer drugs, which MacCready plans to sell at his casino. Along the way, the two grow fond of each other after a rough start, and numerous attacks by the bad guys are foiled by Nick and his skills. Impressed by Parker's martial-arts skill, MacCready hires a Japanese assassin (Sho Kosugi) to defeat Parker once and for all. This leads to an epic sword-fight between the two in MacCready's penthouse, in which Nick eventually wins by knocking the assassin into a hot tub with electricity running through it. With MacCready and his men dead, Billy is reunited with his father. A tearful Frank confesses to Parker that he has long blamed himself for the accident in Vietnam, and Frank is now able to forgive himself. Although now considered "Uncle Nick" to the young Billy, Parker decides to leave Frank and Billy to travel on his own.
