Golgo 13

A small family-run motel hears news of a casino robbery when Golgo turns up to stay. Hank, the son of the family returns home with another man having executed the robbery. The blind mother is suspicious of Hank and is unnerved by Golgo, but the assassin leaves before anything happens. Confronting Hank, the mother accidentally shoots Hank and the accomplice escapes to deliver the money to his boss, without realising that Golgo has been hired by the mob to kill those responsible for robbing their casino.
