Alan Alexander returns from WWI but can no longer do what he did before. Before the war, he was a playright who made people laugh, but after seeing what he's seen, he doesn't think that's enough. He moves his family to the English countryside and, faced with lingering writers' block, takes a walk with his son, Christopher Robin. Inspiration strikes.
Thus is born the Christopher Robin of literary fame, along with his toys, Winnie the Pooh, Eeyore, and more. Surprisingly, the story of a boy and his imaginary friends having adventures in the woods becomes an international hit. Alan Alexander's wife, Daphne, is thrilled that her husband's literary career is finally working out, but Alan Alexander is increasingly irritated that Winnie the Pooh is more successful than his other works. The parents are blind to biggest problem of all - Christopher Robin, who never wanted fame; he just wants his dad.
