Some stories are so beautiful, that you never forget them. In a modern winter sport resort, a pastor tells a family from the city about the Christmas legend of the magical "rock crystal": despite a centuries old feud between the villages Gschaid and Millsdorf, the shoemaker Sebastian and Susanne, the daughter of the local dyer, fall in love. However, the people of Gschaid consider Susanne to be an arrogant Millsdorfer and subject her to their prejudices and hate. Heartbroken and leaving behind her children, the 13-year-old Konrad and the II-year-old Sanna, she leaves Gschaid and returns to her parents. The siblings desperately hope that the magic of the rock crystal, which is said to reunite loved ones, will help bring their parents back together again. When the children get lost in the snowy mountains after visiting their mother on Christmas Eve, the two rival villages come together again.
