Actually, Martin Gruber should finally take it easy after the recent events, but the mountain doctor just can't get any rest. Although his family tries very hard to convince him to take it easy and he moves back to the Gruberhof – expressly only temporarily – Martin can't help but continue to throw himself into his work. He has bad news for one of his patients that he would like to deliver himself. Thomas Mannfeld suffers from a serious cancer. Since the treatment is not working as hoped, he probably only has a few months to live. The passionate astrophysicist would like to use the remaining time with his great love Lisa as best he can, but she doesn't want to admit that she will soon lose him. Suddenly a car accident changes everything: Lisa can no longer remember the past year – the one she shared with Thomas. She first moves back to her parents, although she hasn't had any contact with them for quite some time because they disapprove of her relationship with Thomas. Martin knows: You shouldn't pressurize amnesia patients and confront them with the forgotten events too early. Because Thomas is now almost a stranger to Lisa, he asks him to keep his distance for the time being until the young woman remembers herself. But that can take weeks or months. And without his great support Lisa, Thomas' health is deteriorating rapidly. Will there ever be a "we" for the two of them again? And where will Martin live in the future? Because although he has struck a more forgiving tone recently - living under one roof with Anne is still not an option for the mountain doctor.
