The burnt dead body of a girl is found in the jungle, without any trace of an identity. The CID team try to find out that four girls missing during that recently and realize that this corpse could be any one of those girls. They find out that one of the girls is dead, and that another was last seen entering her building, but that she never reached her house. How could she have disappeared in her own building if not at the hands of the killer? And who is the killer, and is he still hiding in that same building?
ETC.
