'Chatak' is all about a sperm donor's life. An ambitious woman marries a corporate officer, and is economically very happy and satisfied. But, soon she strongly desires to have a child in her life. But the couple’s life turns upside down when they find out that the husband can’t have a baby because of less sperm count. The woman somehow manages to make her husband half inclined and takes the help of sperm donation, and gets her own baby.
