The entire city of Mumbai has gone dark. There's a power supply cut and hence no electricity. Malini believes that it's a cyber attack. But that may not be the sole reason why Adi was brought to the police station. An ancient dagger was stolen from Kala Ghoda Museum. Along with the dagger, some other things were found in the trunk of a stolen car. Since it's a precious artifact, Malini requires Adi's help to solve the case and figure out who's the real thief. It is Adi's knowledge of forensic science and quick thinking that help them find the real culprit.
