Lionel Walk, etter known as Train, is a young black caddy at an elite Los Angeles golf course. There, he navigates between the careless hostility of patrons and the volatile brutality of the other caddies. One day, he finds an unexpected protector: police sergeant Miller Packer, who Train dubs "the Mile-Away Man" for his distant gaze. Packer is investigating a botched and bloody boat hijacking that left a lone survivor: achingly beautiful Norah Still. When the lives of these three people intersect, both violence and tenderness swiftly rise to the surface.
