For Christin Thorstraten, it sounds like a lucrative and, above all, secure deal: being the mistress of an influential politician, with a handsome allowance and a free apartment in the quaint town of Gernhausen. What initially seems like a jackpot to the success-oriented but cold-hearted woman changes when she meets six-year-old Hannah from the neighborhood. The lively, overly self-confident girl captures Christin's heart in no time and shakes her firmly held principles. In Hannah and her grandmother, she finds people who accept the brash and headstrong woman as she is, yet still manage to win her heart. If only Hannah's father Tobias weren't in the picture! Their first encounter ends tumultuously for the two very different individuals, without either of them managing to step out of their own shadows or even admit their true feelings.
