On a weekend break in the Mojave, psychic investigator Mason stumbles across the story of a bygone journalist, Geraldine, who expired in the desert on her way to one of the early flying saucer meet-ups. Unable to shake the pointlessness of the tragic tale, Mason trades a favor with his psychic-world mentor, Hanh, who sends him to the East Coast to attend a wedding where he doesn''t know anyone. Wracked with guilt about his role in disrupting the event, Mason grapples with the cost of intervening in Geraldine''s life, and gains new resolve to change the outcome.
With help from his mid-century friends Billy and Flattop, and with the unflagging support of his boyfriend, Ned, and their roommate, Peggy, Mason shifts to Geraldine''s era, and on a long road trip to Landers, manages to rearrange things enough to shake the foundations of his own timeline.
