Pathram movie starts with the arrival of Nandakumar (Suresh Gopi) from Bombay to join up as the associate editor of a paper called Kerala Rashmi.
Nandakumar finds it hard to adapt to the newspaper owner's policy of increasing circulation by sensationalising news. The story gains momentum when Nandakumar come in touch with the editor of another newspaper called Jagratha, Shekharan (Murali) who is trying to expose the underworld links of Vijayakumar (N F Varghese) who is a big shareholder in Kerala Rashmi.
When Vijayakumar eliminates Shekharan, Nandakumar turns against the newspaper owner and Vijayakumar. He is arrested in a false case filed with backing from politicians and police officials. A young IPS officer Firoz (Biju Menon) who comes in to investigate Shekharan's murder, backs Nandakumar and the duo takes on the goons.
