Munnabhai, our local Bombay goon, and his reliable buddy, Circuit are back! Munna is in love with the voice of popular Radio Jockey Jhanvi. Her effervescent greeting of "Good Morrrning Mumbai" on her daily radio show makes Munna's heart skip a beat each time he listens to her. Life is beautiful for Munna--his "dadagiri" business is flourishing, he listens besottedly to the radio for hours every day, he dreams of marrying Jhanvi. There is just one "minor" problem. Jhanvi thinks Munna is a "Professor of History." And in all her innocence, Jhani even invites Munna to give a history lecture to her family. Poor Munna! What should he do?! As Munna tries to sort of this "minor" entanglement in his otherwise perfect life, Circuit comes up with a bright solution. And then, the most unusual thing occurs in Munna's life. What happens when the 'Present' meets the 'Past'? What happens when our very own "Professor of History" encounters a 'Figure from History'?
