'Undertrial' is based on a true story.
It shows a middle class family man called Sagar Hussain (Rajpal Yadav) who comes from a simple and ordinary family. He had a wife called Sameena (Monica Castellino) and was a father.
His life changed dramatically when he was charged with raping his daughters for as many as 8 years and planning to murder them. Even his wife goes against him.
Is Sagar guilty? If not, then why did his wife turn against him? Why were his daughters quiet?
Even if he is released? Will he be able to regain his reputation and respect?
