Someone is disposing of politicians one by one. And the murderer has borrowed from the genius of Agatha Christie. When a local Mumbai politician is found wrapped in a plastic bag behind a park bench, the dashing and capable DIG Ajay Biswas is told to take over the case. Ajay arrives in Mumbai along with his wife Aparajita and soon discovers he is being misled by his Mumbai compatriots who are determined to save their own skin. Someone is deliberately providing false leads; his presence is not wanted. While in Mumbai, Ajay and Aparajita meet up with their old college friend Akhil Sukumar. Akhil and Aparajita have had a tortuous history, and it appears that the one-time lovers now want nothing more than to let bygones be bygones. Easier said. The privileged flourish at the cost of the oppressed. The price has to be paid, and someone has decided that it needs to be paid in blood.
