Ishwarchand Thakur (Amitabh Bachchan) and Sumitra Thakur (Shefali Shah) are a married couple who run a toy factory together. They have a son named Aditya Thakur (Akshay Kumar) who does not have any interest in responsibility or what he wants to do in life. It gets even worse when he elopes with his girlfriend, Pooja (Priyanka Chopra), the daughter of Natu (Boman Irani). When Pooja gets pregnant, both Ishwar and Sumitra decide to make Aditya realize his responsibilities, as he will have to take care of his wife and child. They take drastic measures and throw Aditya out the house along with Pooja. As a result, he and she live in a room at the back of the house in the garden. The force becomes so bad that Aditya begins to hate his father and they do not speak to each other for a long time. At the same time, Aditya becomes aware of his role in life. However, Ishwar has done all this for a reason and is hiding something from Aditya. Ishwar is trying to make sure that his son is secure because he is suffering from lung cancer and he wants his son to be responsible. Aditya succeeds in becoming a responsible man and also finds out the truth about his father when his father comes for his performance on the stage.
