Rakesh and Sagar are paternal cousins (chulat bhau) and go to the same college. They hail from the rich Sardesai family, which is headed by Aji (Smita Talwalkar) and her sons Prabhakar and Divakar.
Rakesh is in love with Mukta, a simple girl from their college. On the other hand, Sagar is a spoilt, brash, and non-caring, macho guy. Due to an argument, Mukta and Sagar have a cold war and this escalates into a horrific incident – Sagar raping Mukta.
Later on, Sagar is torn by guilt and by his crime. Without admitting his crime, he tries to console Mukta, and later on, he also marries her.
Mukta starts leading a seemingly normal life, but she cannot get close to Sagar due to her memories of the horrible incident. Sagar is patient and understanding but is in constant fear of Mukta discovering the truth.
The story of Oon Paus unfolds as Sagar and Mukta both try to battle their past and lead a normal life as a married couple. Oon Paus marked the beginning of careers of actors Aniket Vishwasrao and Abhijit Kelkar.
