Manche mögen's glücklich (2012)

Lina (Julia Brendler) has an unusual job: As an account manager for an agency in Freiburg, her job is to make it as smooth and easy as possible for newcomers to start the new city. But the heart specialist widower Prof. Markus Gärtner (Stephan Luca) threatens even the good-humored Lina to bite his teeth. With his rugged nature, the renowned physician makes her feel that her efforts are rather annoying. But then he is dependent on her help: The rich Mr. Hofmeister (Heinz Hoenig) wants to invest a considerable sum in the heart research center - until he meets Markus and immediately gets together with him. On the other hand, because of a misunderstanding, the millionaire considers Lina to be the mischievous doctor's partner. In order to win Hofmeister, Lina is said to spend a weekend as Markus' wife - a role-playing game that does not have consequences.
