Sethurama Iyer CBI

Sethurama Iyer (Mammootty) is a CBI officer who keeps coming back to the cases other people have closed. Alex, awaiting execution, admits to six of the seven murders he was tried for, and Iyer cannot let the seventh go, so he starts tracing whoever actually committed it. K. Madhu sets Iyer beside Vikram (Jagathy Sreekumar), the aide who follows him from one lead to the next.
