Inspector Vikram Dev has dealt with some serious crimes and murders in his career, but nothing comes close to this one – The Octagon Case. An architectural marvel – what happens inside it is a mystery. Back-to-back ruthless murders. Baffling messages. One complex pattern. With his sub-ordinate, Raghav, by his side, Vikram races after the anonymous face but soon loses himself between time and life. Will Vikram pick up the scattered pieces and make his move? Or will the masked killer complete his story? Two parallel lives, but one story. The One Story.
