Ravi an educated boy from brahmin family drives Taxi on streets of Bombay. One day early morning meets a beautiful damsel Pooja (Pooja Bhatt) and its romance at first sight.
But the encounter between two of them is too brief.
Ravi (Sanjay Dutt) is constantly haunted by his memories of past and they are driving him mad — friend and Restaurant owner Salimbhau (Avtar Gill) takes him to Hospital but refuses the shock treatment — instead decides to leave the cure in the hand of God.
Incidently Gotya (Deepak Tijori) a matka den owner and another close friend Ravi takes him to red light area which Gotya frequents to meet his fiance Chanda (Neelima) and there he sees Pooja again trying to run away from the brothel of Maharani (Sadashiv Amrapurkar) a Enuch.
Pooja becomes Ravi's obsession — Salim bhai also realises that she might be the cure to Ravi's illness — Ravi puts entire life's savings at stake and sets out to free Pooja from the brothel.
He is able to buy Pooja off from Maharani one first night and is allowed to take her out but Gotya is kept as hostage in brothel.
That is why Ravi is forced to return Pooja to brothel next day in morning but he promises her that he will come back the same night with more money.
That night Maharani having sensed, the oncoming romance between Pooja and Ravi refuses to sell Pooja off to Ravi that night.
What happened to Pooja then?
Will Ravi be able to get Pooja out of Brothel and thus cure his madness that is the violent love story of SADAK.
