Early-retired former police sketch artist Anton Franzen is embittered since cancer killed his wife 4 years ago, hating even more then his Turkish neighbors the 'useless' medical profession, bitching at everyone, except virtually adopted grandson Jens, despite his meddling mother Jenny, hesitant as the knave starts a medical study. Learning so at his 60th birthday, Anton is hospitalized after a cardiac crisis for surgery at Jens's training clinic. Generally liked Croatian nurse Mirjana Maric also wins Anton's favor, until he believes she's siding with her admirer, his cardiac surgeon, Dr. Jan Borsche. Anton turns on her grimly, while befriending Turkish fellow patient Kemal Ates, a professor with incurable long cancer, who introduces him to the secret fun club, which coaches him to try winning her over. Dr. Borsche smells a rat and releases Anton Franzen, who now fakes another cardiac arrest to stay near Mirjana and save her from dismissal by the budget-obsessed hospital administrator Katharina Krüger, who has a crush on womanizer Borsch. An external hospital audit provides a unique opportunity.
