The son of a family is so immersed in work that he is constantly involved with his family. He comes home late every night and this worries his mother. One day, the mother goes to her son's company and without entering the company, calls the boy from across the street to talk to him. Although the mother sees her son in the company, the son lies that he is in a meeting. The mother calls her daughter-in-law and invites them for dinner after complaining, but the boy returns late from work and they do not go to the mother's house. The mother suffers a stroke and dies from grief, but after her death, a letter from her reaches the boy.
