Peace and harmony radiate from the picturesque Alpine town of Mittenwald, and from its residents too, including the sisters Sarah and Juliane. Sarah, the younger one, was always spoiled by her family and always gets what she wants, even if she does so charmingly.

When she realizes that Sarah has also fallen for Philipp, she is ready to renounce her love, for her sister's well-being has always been her priority. But Philipp is unwilling to lose Juliane and makes the situation clear to Sarah ? with fateful consequences...
