In Mumbai, India, Batra Varun, a car salesman, and Deepti, a news reporter, who have been married for seven years and have no children, decided to go to the hospital for artificial insemination. After the transplant was successful, the hospital informed them that the sperm was mixed up with that of another couple named Batra. Varun was very sad and did not want the child for a time and asked Deepti to have an abortion. The other Batra couple was worried about abortion, so they quickly moved upstairs of Varun's house. The two couples went from conflict at the beginning to harmonious coexistence in the later period. July later, the other Batra wife gave birth to a daughter prematurely. Two months later, Deepti gave birth to a son. In the promotional video of the director and his wife of the fertilization hospital, successful fertilization of the patient is "good news" Good News, and the title is a literal translation. Maybe the Hong Kong title: BB Arrives, is a better translation.
