'Remember When' makes a leap of 2 years and returns once again to 1977!

In 1977, we find Mary as the owner of a boutique in Kolonaki, while she is persistently pursued by Mr. Tepentris (Ioannis Papazisis), a charmer, bachelor, and well-known bon viveur in the fashion world and the social circles of Athens. Stelios struggles to make a living as a supervisor in the ministry but is subordinate to Mrs. Argyriou (Emily Koliandri), and a sudden blackout brings them closer together. Nana has taken over the boutique in Gyzi and is married to Dimitris, who is now the owner of a supermarket and a café. Together they lovingly raise little Noni, with the shadow of the absent father Apostolis still lingering. Meanwhile, we find Hermione and Mr. Nikos, who have moved together into Mrs. Roula's old house and are trying to get used to living together as a married couple after so many years of loneliness. Always beside them is Pelagia, who tries in every way to win over the director of their neighborhood police station. Despite her disappointment with the acting world, Elpida persists in trying to succeed alongside Alkis, while Antonis finds love again in Dora (Natasa Exintaveloni), a young and independent journalist from Eleftherotypia, who helps him take his first steps in journalism.
Along with the adults, the young ones also grow up. Angelos (Dimitris Serfas), now 16 years old, experiences his adolescence with introversion. He reads melancholic poetry, engages in photography and cinema, and desperately tries to find his calling. And naturally, he is still preoccupied with girls. His beautiful teacher, his first love Sofia (Ioanna Kalitsantsi) who returns to Athens after many years, his best friend Anna (Konstantina Messini), who is now the third member of their group. By Angelos' side is his best friend, Louis (Vangelis Daousis), who spends his adolescence entirely preoccupied with the opposite sex. He reads magazines with "nudes" in class, steals his father's Vespa to go to clubs, gets drunk, and dares to gather experiences in every possible way.
All of them are heading towards the finish line of the 1970s, with the strong scent of the era influencing their daily lives and foreshadowing the arrival of the iconic 80s. Colorful scenes, foreign songs, new fashions and hairstyles, new habits, clubs, and discotheques will accompany the adventures of the Antonopoulos family and the rest of the neighborhood. New loves, wrinkles, lost daughters, reunions, farewells, unfulfilled desires, stubbornness, and experiments prevail and stir the waters of our familiar neighborhood in Gyzi...

It's early spring and everyone is hoping that some truancy will add a little color, change and intensity to the monotony of everyday life. Dimitris becomes more and more devoted to politics, leaving Elpida to handle things at the cafeteria, while Louis, devoted to winning Zampeta over, makes Angelos an accomplice in a daring plan. Deceiving Mary, but also their headmaster, they make an ambitious plan to skip class and go to the beach. But they are not the only ones who have this idea. Angelos ends up being the baby's nanny for the sake of his parents but, undeterred, he will follow his friends to the beach, even with the baby. Only for them all to witness a spectacle that will bring great trouble to the whole family.
