Dr Trehan and a few others are killed in a hospital lift allegedly by Inspector Singh when the lift stops midway due to an electrical malfunction. Singh claims someone else killed them in the dark. CCTV footage shows there was no one else. Raghav concludes that Prateik entered the lift through a fan vent to kill them. Prateik is also found murdered. Raghav finds out that Matron Dasgupta is the real brain behind all this. Rivalry to control banned drug business at the hospital is the issue.
