Plot

Isow Alex, a convicted serial killer awaiting execution for seven murders, confesses to CBI officer Sethurama Iyer that he committed six of the killings; the seventh was the work of someone else. Iyer takes up the case and sets out to identify the original murderer of the seventh victim.⁵ The investigation brings back Iyer's supporting team: Chacko (Mukesh), Vikram (Jagathy Sreekumar), and the newcomer Ganesh (Vineeth Kumar), with DYSP Sathyadas (Saikumar) of the police on the other side of the inquiry.²^•⁸

The film's climax twist involving Isow and Mosi has remained one of the most discussed moments of the series.³

Production

K. Madhu produced the film himself under his Krishna Kripa banner, and Swargachithra Release handled distribution.⁴ The background score was composed by Shyam, whose theme music for the CBI series became one of its signature elements; Saloo George was the cinematographer and P. C. Mohanan the editor.⁴

Jagathy Sreekumar, who had played the CBI officer Vikram in the first two films, appeared here in a guest role as Memenan Namboothiri, a character who gathers information while disguised.¹¹ The supporting cast included Janardhanan as Ouseppachan, Bharath Gopi as Fr. Gomez, Jagadish as Tailor Mani, Navya Nair as Rachana, Siddique as Balagopal, and Mala Aravindan as 'Kuzhivetti' Mathai.⁴

Place in the CBI series

The CBI series follows the same central trio across decades: Mammootty as Sethurama Iyer, K. Madhu as director, and S. N. Swamy as writer. The five released films are Oru CBI Diary Kurippu (17 February 1988), Jagratha (7 September 1989), Sethurama Iyer CBI (22 January 2004), Nerariyan CBI (9 September 2005), and CBI 5: The Brain (1 May 2022).⁶ Keeping one lead actor, one director, and one screenwriter across five installments is described in Indian film commentary as a rare continuity; even the James Bond films, with a constant lead character, have changed directors and writers.⁹

Sethurama Iyer CBI arrived fifteen years after Jagratha, and its commercial success revived the series after the long gap; Nerariyan CBI followed the next year.¹¹ The character continuity runs through the films as well: Chacko, introduced in the first film as local police, joined the CBI on deputation from Jagratha onward, and by the fifth film he was described as the officer with the longest CBI deputation in the state.¹¹

Reception and legacy

A contemporary Nowrunning review called the film an intense suspense thriller that keeps up its pace throughout, praising Mammootty's performance as the CBI officer and Saikumar as the police officer, while criticizing Mala Aravindan's comic track and the romance between Navya Nair and Vineeth Kumar as weak points.² The film's roughly 160 million (16 crore) gross made it the top Malayalam earner of 2004.³

The film is credited with fixing the character's mannerisms in popular memory: the hands clasped behind the back, the sharpened, questioning speech, and Iyer's Tamil-inflected Malayalam, details that carried into the later installments.³ A 2024 report stated that a sixth CBI film, to be directed by Jofin T. Chacko, was in preparation, though without official confirmation at the time.¹⁰ As of a recent check, the film was not available on any streaming service in India.⁷
