Halis Korhan is the owner of a large jewellery empire and the head of the Korhan family. Even though his son Orhan and oldest grandson Fuat run most of the business, he still makes the most important decisions in the company. His younger grandson Ferit, who is the total opposite of his brother Fuat, is a very irresponsible young bachelor who just returned from abroad where he went to study. Halis can’t take anymore of Ferit’s recklessness and he charges his widowed daughter-in-law Ifakat with finding him a nice girl to marry.
The news that Halis Korhan is looking for a bride for his grandson, comes like a bolt from the blue into Kazım’s mansion in Gaziantep. Kazım’s only hope to get rich are his beautiful daughters, Suna and Seyran. After Ifakat sees Suna and decides she is the right girl for Ferit, the family goes to Gaziantep to ask for Suna’s hand in marriage. But before the ceremony, Ferit and Seyran meet each other without realizing that they are supposed to become brother and sister-in-law, and Ferit is totally captivated by her.
The two sisters’ lives change forever when Ferit decides to marry Seyran instead of Suna. While Kazım is glad that he has secured his access to a great fortune, Seyran will be the new bride in a family full of betrayals, lies and secrets.
