ONCE AGAIN is a light comedy which chronicles the parallel romantic adventures of a mother and a daughter.
Anna (Danuta Stenka) is an energetic and attractive 40-year-old with a great sense of humor and an easy going attitude towards life and fashion. Her 19-year-old daughter Kasia (Anna Antonowicz) is not a typical teenager; she doesn't like to party, she's not interested in boys, and she eats healthy food and practices yoga.
Michal (Jan Frycz) is a very handsome, serious and well-off lawyer. Pawel (Przemek Cypryanski) is twenty, loves life, beautiful girls and partying.
Kasia and Anna are supposed to spend vacation together at a seaside resort. Instead, Kasia goes off on her own while Anna, with a group of her friends, decides to rest in the mountains.
