[1] Jayarajan, an over-enthusiastic assistant manager at a tea plantation plans to loot a huge amount from the company.

Jayarajan, who already was having an affair with Padma (a nurse of the Plantation Hospital who is money-oriented and having a loose morality in relations with men) now eyes Devi.

Cop Ravi starts investigating Jayarajan's past and finds some loose ends, but he gets no solid proof in this regard.

In a strange turn of events, fearing faint-hearted Joseph might spill the beans of the Manager's murder, Jayarajan finishes off Joseph in an orchestrated jeep accident and Padma, by strangulation, mimicking a suicide without any trace of suspicion about the two murders to anybody except Chandran, whose silence Jayarajan buys with scare tactics.

But before he can kill Devi, Chandran informs Vasanthi the truth about the death of Menon and both succeed in calling the cops.
