A BIG BOLD BEAUTIFUL JOURNEY is the story of two individuals taking the journey of their lives. David (Colin Farrell) is all set to leave to attend the marriage of a friend at a holiday boutique resort. His car is clamped by the traffic police, supposedly for incorrect parking. He
sees the ad for a rental agency and approaches them. The agency is run by two mysterious people (played by Phoebe Waller-Bridge and Kevin Kline). They offer him a vintage 1994 Saturn car and insist that he take their GPS device as well. David agrees. He reaches the wedding venue, where he bumps into Sarah (Margot Robbie). Sparks fly between them, but David stops himself from going all out. The next day, Sarah's car breaks down and David offers her a lift. The GPS suddenly starts taking them to places from their past and does everything possible so that they begin a love affair. What happens next forms the rest of the film.
