Although Memo (Aras Bulut Iynemli) is tall and strong, he has only the wisdom of a 6-year-old child. He lives with his daughter Ova (Nisa Sofiya Aksongur) and his grandmother Fatima (Celile Toyon Uysal). Although life is tight, the reunion of the family is the greatest happiness. Who knows that one day a disaster will come from the sky. Memo, who is unwilling to step on an ant to death, is actually charged with an unwarranted murder and is locked up in cell No. 7. The simple Memo does not know what tragic fate he is about to face. In prison, Memo soon became friends with his cellmates. Memo's cheerful and optimistic personality infected everyone around him, bringing them happiness and hope. In order to repay Memo, these once "extremely evil" criminals decided to use their lives as a bargaining chip to realize Memo's long-cherished wish.
