In a small town dime store in West Texas, the "Disciples of James Dean" gather for their twentieth reunion. Now middle-aged women, they were teenagers when Dean filmed Giant two decades ago in nearby Marfa. One of them, an extra in the film, has a child whom she says was conceived with Dean during the shoot. The ladies' congenial reminiscences mingle with flash backs to their youth; then the arrival of a stunning but familiar stranger.
