Qatil Makkhi Part 1

Nayyar is accused of murdering his personal doctor. He claims in the court that the doctor was forced to jump off the balcony by a housefly. Ramesh Shukla, who is a staff at the doctor's clinic, claims that Nayyar pushed the doctor from the balcony. Inder Mohan Jaiswal, the prosecution lawyer, proves that Nayyar has fear of needles and injections. Jaiswal points out that while the doctor was trying to administer an injection to Nayyar, he was inadvertently pushed by Nayyar. Later, K.D. Pathak, who is representing Nayyar, learns of two deaths, which are unrelated to the case. Surprisingly, two people have lost their lives after seeing a housefly. How is the housefly related to the murder case?
