The wait is over. The lovable duo of Sanjay Dutt and Arshad Warsi are back this Friday with the comic caper "Lage Raho Munna Bhai", a sequel to their 2004 superhit "Munnabhai M.B.B.S.".

If "Munnabhai M.B.B.S." saw Munna creating an upheaval in a medical institution, part two will see him running around a radio station because this time he falls in love with a radio jockey played by Vidya Balan.

Director Rajkumar Hirani moves into the realm of the philosophical as well. Through the film, Hirani makes an attempt to prove that Gandhian philosophy continues to be relevant today.

The story goes something like this:

Munna (Sanjay Dutt) is a tough goon with a heart of gold. He confronts every situation with his unique streetwise attitude and humour. But even Munna's successful 'dadagiri' methods are tested when love takes him for an unexpected historical tour.

Munna falls in love with the voice of popular radio jockey Jhanvi. Her effervescent "Good Morrrrning Mumbai" makes Munna's heart skip many beats. While listening to her shows, he dreams of marrying her.

Jhanvi is also bowled over by Munna's rustic charm. The only problem in this perfect love story is that Jahnvi mistakes Munna for a professor of history and invites him to give a lecture on history to her family. And that is where all the trouble starts.

Munna doesn't know how to sort out this entanglement. His trusted buddy Circuit (Arshad Warsi) comes up with a bright solution. And then, the most unusual thing occurs in Munna's life - he encounters a figure from history.

What happens when the present meets the past?

There is another problem in Munna's life and his name is Lucky Singh (Boman Irani), a contractor hankering after money. But Lucky Singh's daughter, Simran (Dia Mirza) challenges traditional ideas with her independent views and shows her father that there is more to life than money.

Produced by Vidhu Vinod Chopra, the film is expected to have a bumper opening.
