What if you could open a doorway and walk through it to re-live a defining moment from your past? Sarah (Margot Robbie) and David (Colin Farrell) are single strangers who meet at a mutual friend's wedding and soon, through a surprising twist of fate, find themselves on A Big Bold Beautiful Journey -- a funny, fantastical, sweeping adventure together where they get to re-live important moments from their respective pasts, illuminating how they got to where they are in the present... and possibly getting a chance to alter their futures.
