It is about a woman named Shamsi who is in prison after an accident. She takes a 15-day leave from prison to sort out the life of her only son Khosro, who is also a criminal, and proposes to her brother's daughter, Heshmat, who is an old cinema owner, for her son. Heshmat, who does not have the courage to say no to her sister, tells Shamsi a new lie to get her started, unaware that this seemingly small lie will ruin everything.
