Based on a true story, this charming film, which will appeal to adults and children alike, explores the relationship of the extraordinary black bear who became the inspiration for the stories of A.A. Milne, and the heroic man who saved her life and gave her to the world.

August 1914. The outbreak of World War One. The Canadian city of Winnipeg is gripped by a patriotic frenzy. Troops march through the heart of the city as young men in civilian clothes rush to join the ranks. Among the troops is Lieutenant Harry Colebourn (Michael Fassbender, Alien Covenant, Assassins Creed), a supremely confident and likeable vet who has a gift with animals.

But Winnie (Winnipeg) is a breath of fresh air from the harsh realities of war for the soldiers and is given a reprieve by old fashioned General Halholland (David Suchet, Poirot, Henry VIII) by becoming the regimental mascot.
