With flights suspended at airports, Berat tries to escape by car from the harsh Turkish winter and the pain of having lost his wife, traveling with their two children: Ferhat, four years old, and Volkan, two, to Georgia.
Unexpectedly, a rock slides across the road, causing it to overturn and leaving Berat and the children trapped by their seat belts.
Efé, who was returning from a family wedding, next to his wife and also their six-month-old twin children, did not think twice before parking the vehicle on the side of the road and saving that man and his children.
After saving Berat and the boys from death, a strong friendship begins between them, making both sign a Marriage Contract between their children Ferhat and Luna.
Twenty-one years pass, Ferhat and Volkan study and graduate in the USA and when they return to Turkey they start working at their father's Automobile Company.
Volkan became a famous basketball player, but abandoned his career to be his father's right-hand man in business.
His brother Ferhat despite being the eldest son, is nothing more than a seductive bohemian, who will steal the heart of Rabia, the daughter of his father's partner.
The beautiful Luna will grow up knowing that one day she will have to marry a man she has never seen, but destiny will cross her paths with Volkan in a charity basketball match, in favor of the homeless of the earthquake, making a beautiful story of love start for them.
Never having been touched by a man, Luna will be kissed by Volkan, who will fall madly in love with her.
Upon discovering that Luna is his brother's betrothed, Volkan will despair and will do the impossible for the Marriage Contract to be undone and for him to marry in her place.
