Lilla, a forty-something couples therapist devoted to her family, is blindsided when her husband suddenly leaves her for a younger nail technician. Struggling with heartbreak, Lilla finds herself being pushed by her headstrong daughter, Zsófi, and her no-nonsense mother, Vilma, to snap out of her depression and start dating again. In a bid to lift her spirits, Vilma introduces Lilla to a charming journalist — but things take an unexpected turn when Zsófi discovers a potential match of her own for her mother.

Lili is a typical girl of our time: she's lonely and tries to convince herself that this is what's good for her. But one day, she finds an old package of letters in her parents' apartment, which her mother apparently didn't want to show her at all. Of course, she doesn't hesitate much, she starts reading, and the past comes alive... an unforgettable summer in the early 1990s, when three good friends are on vacation at Lake Balaton, and of them, only Eszter wants to stay faithful to her boyfriend who left her at home, who swallowed a stake. But her plans, which she usually follows with engineering precision, are slightly messed up when she meets Gergo, easygoing, funny and has another very good quality: he plays in a band and performs with his friends on the beach in Szigliget in the evenings.
