What if someone wasn’t just watching you… but studying your fear? Across India, young women begin disappearing without a trace. There are no signs of struggle. No witnesses. No evidence. Just one chilling detail. They were all last seen alive online. Crime journalist Aarohi Mehta notices a disturbing pattern the police can’t ignore. Each victim vanishes within the same precise time window. Each shows signs of emotional withdrawal before disappearing. And someone is always observing. But this killer doesn’t hunt bodies. He hunts minds. As Aarohi digs deeper, she uncovers a twisted psychological experiment built on surveillance, isolation, and fear. The closer she gets to the truth, the more personal the case becomes—until she realizes her own past may be connected to the origin of the Observer. Every message is calculated. Every move is monitored. Every fear is weaponized. And now… she is no longer just the investigator. She is the next subject.
