The trailer starts-off with a horse named Joey running to an unknown destination. In the next few seconds, a young man called Albert Narracott finds it and bonds with the horse. The soft conversion between Joey-Albert and the horse's encounter with several people give hints about the story.
According to director, the story explores the friendship between Albert and Joeys. The young man, who trains and tames the horse, was forcefully separated when it was sold to the cavalry. While the horse was sent to serve on the battlefields during the World War I, Albert moves to France.
