In a housing society every house is under panic as the water coming in their taps is red in colour and the suspect it to be blood. CID investigations reveal that there is a body with its throat slit in the overhead water tank of the society. The body belongs to Mr. Rana who was supposed to come back from a short tour at night. The watchman too had seen him come in an auto. But why would someone kill him and then do the herculean task of taking the body all the way up to the water tank?
