After the homicide of Kamini, a girlfriend of champion chess player, Tej Pratap, CBI Chief S.K. Singh summons three agents, Badal, Roochi and Damini (nicknamed Barood) to investigate this incident. The trio are delayed after Roochi gets abducted and Badal rather dramatically rescues her in Europe. The only clue the trio have is the word 'Revenge' inscribed near the deceased' body. Their bafflement will increase when another female gets killed and this time the word written on her person is 'Is'. Damini suspects Tej, and accordingly confronts him, but he seemingly retaliates, and she shoots him on the hand. He is subsequently apprehended, denies ever having killed anyone, and alleges that the real killer maybe someone else. Before they could ascertain if he is telling the truth or otherwise, the agents find the murdered body of another victim, a male named Awadh Narayan, and the word written this time is 'My'. They must rush to put together all possible clues in order to nab the killer(s) and prevent him/her/them from carrying out her/his/their gruesome task.
