"Clara Stahlbaum (Mackenzie Foy) travels to the fantasy world the Four Realms - Land of Amusements, Land of Sweets, Land of Snowflakes and Land of Flowers - in search of the key that will unlock an egg-shaped box, which was a gift from her mother."

"There she is accompanied by Nutcracker Captain Phillip Hoffman (Jayden Fowora-Knight) and together they have to overcome the dangers that await them and solve the mystery of the message included with the box: 'Everything you need is inside'."

Side notes:

The final scene with ballerina Misty Copeland dancing is beautiful, but i'd have preferred that the movie ended where Clara dances with her father in the gazebo.
