Sethurama Iyer CBI

Sethurama Iyer CBI Malayalam is a 2004 Malayalam mystery crime film directed by K Madhu, written by S. N. Swami, and starring Mammootty, Mukesh and Jagathy Sreekumar.

The movie begins with Sethurama Iyer Mammooty visiting Isow Alex Kalabhavan Mani, a convicted serial killer who is awaiting his execution. Alex was arrested and convicted for the coldblooded murder of seven people in two different families. Alex, who had been living a wild life then, had committed the crime high on narcotic drugs. The murder case was left to the CBI for investigation and an able officer, played by Siddique, nabbed Alex in no time. Alex is now a new man, mainly due to the influence of a priest Gopi, who requests Iyer to visit Alex.What Alex tells Iyer is startling he didnt commit one of the seven murders he was convicted for. The murder was that of Manikkunju, a businessman. Manikkunju, along with his daughterinlaw Mosi, was murdered at his house. Alex tells this all the same confessing that he murdered Mosi. The possibility of another killer involved is very remote and Alex is a serial killer who thoroughly denied any hand in the murders when he was arrested, but yet Iyer decides to reopen the case and investigate. He faces many odds to prove Alex right would be proving his own bureau wrong and to prove Alex wrong would be wasting time and money. ........
