Three couples, six friends and the threat of retirement age: when TV journalist Paul quits his job at the age of 65, neither he nor his wife Christiane (59) had any idea that their relationship would be put to the test. Neither did personnel manager Marlene (62) suspect that her husband Klaus (64) had been having an affair with a younger woman for years, who is now expecting his child. And everything changes between high school teacher Heiko (63) and his wife Vera (62) when he is diagnosed with a brain tumor. Three couples, six people and the 60-plus agenda: what remains is their friendship.
