Ryu, still living in rural Japan, receives an unexpected letter from his old friend and sparring-partner Ken Masters. He invites Ryu to visit him in the United States, as they have not seen each other for many years. Ryu thinks about the request and decides to travel and see his best friend. They meet at San Francisco airport, where a big limousine is waiting to drive them home to Ken's place. Ryu is impressed by the riches of Ken's family. After relaxing, the 17-year-old boys go out for the night on Ken's motorcycle and bribe their way into a pub called Mt. Fuji. Ken angers some soldiers by flirting with one of their girls and a fight ensues. After the military men are defeated, their Sergeant, Guile, appears. (Source: Wikipedia)
