Jail Neil Nitin Mukesh as Parag Dixit
Parag seriously believes he's God's chosen child.

He has his path carved out for him up ahead and is very impatient about getting there...until one fateful evening when everything changes!
Mugdha Godse as Maansi
Parag's love interest and an independent woman who lives life on her own terms. Maansi has never asked for the commitment yet because she would like Parag to arrive at the decision himself and she loves him too deeply to question the imminent commitment. A bond that only gets deeper and sealed across the bars because Maansi is Parag's only ray of hope outside the Jail and the reason to go on despite all hurdles. Maansi is Parag's resolve.
Manoj Bajpai as Nawaab
No one knew Parag's strength except for Nawaab. In his mid- forties, Nawaab is considered honest and humble. He has already served 10 years of his 20 year jail sentence. Very few people know Nawaab's real story and fear him for it. Compassionate yet ruthless when required, Nawaab is the conscience of the story and Parag's moral compass provided; Parag is willing to listen to him.
