"Their Lucky Stars" is a charming summer-holiday-vibe story of love that appears in unexpected circumstances. The peaceful and organized life of Robert (Piotr Adamczyk), a symphony orchestra musician and single dad to a ten-year- -old boy, Filip (Maks Balcerowski), takes a sudden turn when Marta (Roma Gasiorowska), a charming and energetic popular fitness star runs into it. Two dissimilar characters, two different takes on love and life. Marta has her own TV-shows and writes culinary books, and her face appears on the covers of the most popular magazines. Robert is a walking denial of the "sporty way of life". A go-getting celebrity and a man intimidated by her charm. Why did fate bring them together? Will they be able to find their happiness with each other?
