They were childhood friends with little in common except for the musical background of their respective families. While Arjun was consumed by a passionate drive to get on stage and realise his grandfather's unfulfilled dream, Mannu had little interest in his music tutor father's instruments and was content with remaining a child at heart with no higher ambition than enjoying the good things in life.

But little did they know as they grew up that someday it would be music that will bring them together - and drive them apart.

While Arjun ends up in London and works his way up from the streets to forage a band - London Dreams - with Zoheb and Wasim, two Pakistani brothers, and Priya, a music enthusiast from a conservations South Indian family, far away in Punjab, music becomes just a mere survival tool for Mannu, who takes to playing at weddings in the village.

Then Arjun does what good friends do - brings Mannu to London to become a part of London Dreams - and soon regrets it.

Overnight, the irreverent Mannu, with his inherent musical gift, effortlessly achieves the adulation and glory that had taken diligent Arjun years of struggle and sacrifice.

But when Arjun also loses Priya, the giirl he secretly loved to Mannu, he battles his inner demons to devise a sinister strategy to destroy his best friennd. As the band goes on a three-city tour of Paris, Rome and Amsterdom, Arjun meticulously sabotages Mannu's career and love life...

Finally, at Wembley, one of Europe's largest stadiums, where he hopes to have his moment of glory, a rude shock awakens Arjun - at the expense of his band, his friendship and his credibility - a humbling experience that teaches him the true meaning of acceptance in life.
