Sethurama Iyer CBI

In this Malayalam mystery thriller, CBI officer Sethurama Iyer is drawn back into an old case after visiting a condemned serial killer awaiting execution. The convicted man, who years earlier was caught for slaughtering members of two unrelated families in a single drug-fueled night, now claims he did not commit one of those killings, a double murder of a businessman and his daughter-in-law. Convinced there may be truth to the confession, Iyer risks his reputation to reopen an investigation that could either vindicate the killer's claim or prove it a costly waste of time.
