After having been missing for four years and presumed dead, Travis emerges from the desert near the Texas-Mexico border and collapses at a gas station. His younger brother, Walt, a billboard artist, takes him to Walt's Los Angeles home where Travis' son, Hunter, has lived with Walt and Walt's wife, Anne, since Travis and his wife, Jane, disappeared. Travis reestablishes a relationship with Hunter, finds Jane and brings about a reunion between Jane and Hunter before leaving again.
