Three different people die by jumping in front of a speeding train on three different days. On investigation, Raghav finds that all of them were witnesses in a hit and run case. They had given false testimony, for money, to turn it into a road accident. The fourth witness, Nirmal Saluja, was cheated of his share of money by the other three. Nirmal, a trained psychiatrist and an expert in hypnotising people through telephone calls, used this method to take revenge by killing them one by one.
