When your parents die in an accident, you and your sister are suddenly in a precarious financial situation. To outfit their laboratory, your parents relied heavily on loans by the Stern Group. Yet, the medical equipment they were developing is still a prototype with little financial value. With the prospect of having to drop out of college to find work looming over you, you decide to visit Mrs. von Stern -the CEO of the Stern Group- at her office. Your only hope is for her to take pity on you and defer the loan for a few years. Instead, Mrs. von Stern offers you a deal: If you and your sister serve as household staff at her estate over the summer, the debt will be forgiven. She only asks one thing of her servants: Total obedience.
