The movie unfurls with Harpreet Singh Bedi [Ranbir Kapoor] who is just an average student who anyhow manages to pass. The less ambitious Harpreet unlike his friends doesn't go in for higher education but opts for a Salesman's job. He lands a job as a trainee at AYS Computers and within a few days is blasted for being a 'Mahatma in the jungle.' He complains against an employee of a firm who buys bulk orders from AYS because he is asking for his 'Cut'.

AYS boss and their sales manager see red. He is insulted and asked to make just 'cold calls' from his desk. Harpreet then hits upon an idea to start his own parallel business naming his firm Rocket Sales. He gradually ropes in all the key staff members of his own office making them equal profit partners and soon becomes a big business threat to AYS. The rapidly sliding company's sliding sales figures rattle Puri. What happens to Harpreet and his Rocket Sales team after Puri tries to find who his major competitor is, forms the rest of the film.

Performance wise, Ranbir has proved his talent. He has given a brilliant performance. Manish Chaudhry as a boss is great. Gauhar Khan is very impressive. Shazahn Padamsee the debut lead actress is excellent.

On the whole, Rocket Singh - Salesman of the year is a decent film. This is really a commendable work by Shimit Amin that delights, inspires, educates and enlightens.
