The police report that the door was closed from the outside using a different lock, the room was a total mess and Kannan was hanging from the fan with a pool of blood on the floor.

Muthu and his colleagues enlist the help of Inspector Jayant Sakhalkar from Chembur Police Station to conduct an inquiry into Kannan's death.

As the inquiry goes on, it is revealed that Kannan planned his own murder with the assistance of his two other friends, Arul and Abbas, unable to get out of the debt he was in at the time.

Nobody including the hotel receptionist, workers or other occupants heard a single sound of Kannan getting attacked and his fingerprints, which contained blood stains, were on the switchboard and the fan.
