Fifty-something years later, she's wondering. did she get on the wrong bike?Now retired, Keith basks in a couch-potato lifestyle, streaming The Orville and Star Trek episodes all day.

The therapist uses an unorthodox method - a time-traveling Volkswagen van, to cast them back to those four days of Eden in '69, where they first met.
Will the freedom and self-discovery of Woodstock lure Keith or Cash to seek a new romance? Or can grooving to Déjà vu and love.. lead them back to the harmony they once shared?
