In the dark corner of Mumbai City a new leader by the name of Babban Singh has risen to rule the gangster underworld.

Cruel beyond imagination, psychotically violent and far more devious than any gangster the city has ever known.

Babban perceives other human beings as objects who he uses for his own amusement by playing games with his victims.

He does not engage in conversation but when he speaks, he does so to voice his own thoughts.

Heero (Ajay Devgan) and Raj (Prashant Raj) are two young men who arrive in the city of Mumbai with big dreams of making it to the top.

It's another matter that Heero and Raj are jobless and don't have enough money even to buy a decent meal.

Childhood friends, their loyalty is absolute, with the younger Raj looking up to the elder Heero.

There is also Narsimha (Mohanlal) whose eyes retain composure at all times. Dark circles collected over sleepless nights betray the fact he is a man tormented by his own past.

Nobody has ever seen Babban Singh and if they did, they didn't survive to tell the tale. But one man believed in his existence. And that is inspector Narsimha, an encounter specialist.

Durga (Susmita) is a trained nurse. Her life blossomed when love happened. But then, tragedy struck. Dignified, silent, her demeanour hides an inner strength that at times raises itself beyond what one would expect from a woman.

Ghungroo (Nisha Kothari) drives a 'rickshaw' named 'Laila'. Laila is her best friend and confidante. Ghungroo is Mumbai city's only woman rickshaw driver who knows all the shortcuts.

She'd like you to believe she's a man. But deep inside, she is all woman.

Heero and Raj arrive in Mumbai and find work with Shambhul Seth, a criminal with heavy underworld connections.

In his pursuit of Shambhul, Inspector Narsimha comes into contact with these lads. On meeting them, he realises that these were no hardened criminals. Small time hoodlums perhaps, but deep inside, their values were still intact.

In a deadly encounter with Shambhul Seth, Heero and Raj display their bravery and fearlessness to Narsimha. But the two are also arrested and sent to jail for a while.

Much later, when Inspector Narsimha needs help in his hunt for Babban Singh, his brief impression of Heero and Raj returns to him. He decides to enlist their help.

How Heeru and Raj captures Babban Singh forms the crux of the story.

Said to be inspired from the all time classic Sholay, director Ram Gopal Verma gives his own interpretation.

The same number of characters have been employed but their names have been changed from the original classic.

The dance number, Mehbooba Mehbooba, performed by Urmila Matondkar forms the high point of this thriller whilst the original number performed by Bollywood dancer, Helen was a worlwide rage.

Ram Gopal Ki aag is released by Adlabs Films in the UK.
