Plot

A musician finds himself on the run from a group of thugs with his friend and his estranged parents.

The film starts off with Inder Bhalla (Abhishek Bachchan), an aspiring song composer getting kicked out of his house by his father, Bhajanglal (Rishi Kapoor). Bhajanglal runs a bakery that doesn't really "run". He wants Inder to work at the bakery, but due to Inder's ambitions on becoming a successful song composer, he clearly refuses. Bhajanglal finds this an insult and sends Inder out of his house thinking that he is arrogant and selfish. This makes Inder hate his father forever but somewhere inside his soul, Bhajanglal still has love for his son.

Inder travels to Thailand with his friend Ronny (Sumeet Vyas) who is also an ambitious song composer. Inder misses his mother, Pummy Bhalla (Supriya Pathak) but hasn't talked to her in many years. Suddenly, Inder gets a phone call from Cheema (Mohammed Zeeshan Ayyub). Cheema lies to Inder that his father has sold his bakery and wants him to get his share. Unknown of this lie Inder leaves everything and flies back to India.

At the airport he hugs his girlfriend, Nimmi (Asin) goodbye unknown that she is also travelling to India on the same flight. When Inder and Nimmi reach India they catch the same taxi as Nimmi wants to visit Inder's place. Inder drops Nimmi at his place and then goes to Cheema. There he sees his father has been abducted by Cheema and his goons. Inder comes to learn of the real truth that over the years his father borrowed lots of money from Cheema due to house needs but couldn't return it. Cheema warns that if wants himself and his father to stay alive then he better arrange money.

Inder and Bhajanglal go home to think of something. There Inder finds out that his mother is suffering from Alzheimer's and Bhajanglal sent her to an ashram. Inder thinks that his father was very selfish, but he hasn't learned the truth yet. Bhajanglal says that Pummy had converted her house savings into jewelry and given the same to her brother for safe keeping. So, the idea is to retrieve the jewels from Pummy's brother.

Inder, Bhajanglal, Pummy and Nimmi take a road trip to try to run away from Cheema. Cheema is in hot pursuit, as the group hurtles from one obstacle to another. They reach Kripal's (Pummy's brothers) house only to find that he is dead. They find a bank locker key that Kripal left behind for Inder. They go to a bank on their way and want to take Pummy's brother's money that Pummy has right on. Pummy obviously has lost her memory, so Bhajanglal has to sign the form. There, Inder learns that his father has divorced his mother. And as such, there is no way that the locker can be opened with Pummy signing the documents. This causes his hatred for his dad to increase. Bhalanglal tells Inder that it wasn't his fault and the dark truth behind his and Pummy's divorce.

The film goes in flashback. After what he has learned, Inder realizes that his father was always innocent and starts loving him again. Bhajanglal explains that Pummy was taken away from him by Kripal's wife after Inder left, and they sent the divorce papers as they wanted to stake a claim to Pummy's divorce settlement. But when they learned of Pummy's Alzheimer, they sent Pummy back to Bhajanglal. Bhajanglal got into a debt trap with Cheema only to get funds to treat Pummy.

Inder sells all his songs that he had composed to pay back Cheema, gets his parents married again, marries Nimmi, and renovates his and his father's bakery. The film ends with Inder, Nimmy, Bhajanglal and Cheema (now their friend) working at the bakery and making lots of money.

Sonakshi Sinha appears in a song Nachan Farrate just before the interval when Inder's family go to a Dhaba but do not have the money to pay for the food. Sonakshi works at the Dhaba as a dancer, but his co-dancer is drunk and cannot dance anymore. Sonakshi offers Inder free food if he agrees to dance with her.
