Joe Müller, a single father, is electrified: in front of him stands an outraged woman who insults him badly. Still, he falls in love. As it turns out: not exactly the right one. Tessa, who is in the hospital with her son, is upset because her counterpart does not apologize for the accident caused by his daughter. But then she also finds Joe more than just nice. When Joe finds out that the magical Tessa is the new, ambitious CEO of the architectural firm "Planfactory", who has given him notice without even knowing him, he plans a revenge campaign.
