Katharina, a young lawyer from rural Kleinpenning, has made it big in Munich by her own efforts. Only her relationship life can be optimized, because the attractive single woman has the highest standards: even in this cosmopolitan city, only twelve candidates are suitable - purely statistically speaking! And none of them have been on the carefully selected online dates. The possibility of meeting Mr. Right in her home town and by chance would never occur to the woman from Munich. When Katharina has to look after her mother Johanna after a fall at home, she hires Mike to renovate her parents' house to make it suitable for senior citizens. The fact that her mother immediately takes a liking to the good-looking master carpenter as a potential son-in-law is actually already an exclusion criterion for Katharina.
