After a bruising encounter with a terrorist group, Detective Kamil Rahman has decided to hand in his resignation to the Met and set up a detective agency with his friend Anjoli. But when his boss asks him to go to India to investigate the murder of a British engineer who was found with eighteen arrows stuck in his body, Kamil agrees to take the case, as long as Anjoli can accompany him.
When they arrive in Mumbai, they find someone is on a gruesome killing spree, striking down those connected to the engineer in increasingly macabre ways. Meanwhile, an old friend of Kamil's gets in touch to beg for his help: he believes his family are cursed, and that he is going to die on his 47th birthday, just like his father and grandfather before him.
As the body count rises, Kamil is torn between solving a very real murder case and protecting his friend from a grisly - if far-fetched - fate. Can he catch a killer and prevent an ancient curse before more people lose their lives?
