Detective Arjun Arora feels his life is crumbling around him. His father has passed away, and he cannot forgive the corrupt police officer who sent Arjun into a coma a year back. And then, a young widow visits him and presses him to take on a new case: to investigate her husband's mysterious death. Rohit Vats was a pharmaceutical company executive who had recently returned home to Delhi from a work trip to China. Soon after, he turned up in a seedy part of Kolkata-dead. Was it a love affair gone wrong, geo-political intrigue, or corporate rivalry which led to Vats' death? Arjun finds that Vats might have been looking into illegal wildlife trafficking and zoonotic diseases like SARS. Increasingly, it appears that the answer to the mystery might lie in China.
