Austria 1945. After losing his family, Jakob shelters with Herr Engel in a rural stable, where they hide the precious Lipizzanner stallions they know Hitler wants to steal. When a German officer comes looking for Jakob and finds the horses, Jakob and his guardian know they must get the stallions to safety, but the only way is straight through Nazi territory. Joined by Kizzy, an orphan Roma girl, the three must guide the horses across the perilous Austrian mountains. Will they reach safety? What will be waiting for them on the other side?

In the chaotic last days of World War II, Jacob and Kizzy are tricked into a life or death journey. Heinz, their guardian, thinks they are simply helping to fetch some rare horses, but they are really being used to get over the border. Far from home, they are attacked and only just escape. They hide in a seemingly deserted mansion, but they keep hearing strange noises… Investigating, they find it shelters not only forty abandoned horses but a small band of lost children, displaced by the war. With danger on every side, can Kizzy and Jakob keep them safe and get them all home?
