'Goodbye Christopher Robin' tells the story of famous children's story writer A. A. Milne and his relationship with his son, Christopher Robin, whose games and iconic stuffed animals inspired the author to write one of the most well-known children's stories of all time: 'Winnie The Pooh'.

A. A. Milne's approach to the success of his books opposes his son's naive and infantile vision bringing us a unique point of view that showcases the magic of a little boy's games in contrast to adult's reality. Together with his mother Daphne and his nanny Olive, Christopher Robin will embark on a magical journey with his animal friends who will come to life before his very own eyes. The film not only highlights the success of the authors work, but also reveals the strain the family felt over their new-found fame.
