The single mother Leonie is a self-confident and sensitive young woman. The cosmetics saleswoman leads a modest but happy life with her nine-year-old son Valentin. Now, however, she is facing a huge problem: her ex-boyfriend, who moved abroad some time ago, left Leonie with an immense mountain of debt - and the young woman cannot possibly pay it off with her small salary. In this emergency, her friend Stefanie has an apparently saving idea: the pretty Leonie should simply catch a rich man, that could solve all financial problems suddenly. Although Leonie has scruples at first, she finally places a personal ad - her dream prince is already in the immediate vicinity: namely, the likeable Oliver, who pretends to work as a temporary worker in the department store, is in truth the heir of the department store mogul Schönthal. In this way, he would like to get to know his future employees incognito - and fell in love with Leonie straight away. He is delighted to note that all wealthy marriage applicants turn out to be true rivets. But even he does not succeed in winning Leonie over - although the young woman senses that she feels more for Oliver than just collegial friendship. But instead of following her heart, Leonie is still looking for a solvent partner. She seems to find it in the real estate agent Kai Wesselmann: he is as rich as he is generous, charming, looks good and has a heart for children. In short: a real dream man. But the more serious the relationship with Kai becomes, the more Leonie doubts her decision to get involved with a man she doesn't really love because of the money. Until Valentine's birthday, which Kai organizes as a pompous but soulless children's party, two men stand in front of her, both of whom want to ask for their hand. Leonie has to choose.
