Plot
Ashoka Varma, an honest police office, is murdered while trying to find evidence in a smuggling case. CID Ramdas (Dasan) and Vijayan are invited to Kerala to find the murderer.

Once in Kerala, Dasan overhears a conversation leading him to mistake Isaac and Prof. Vidyadharan, two bird watchers, as the murderers. Dasan and Vijayan follow Isaac but they are shot at and ambushed by a group of men. They are rescued by Prabhakaran Thampi, who is the real murderer and a smuggler. He pretends to be a philanthropic businessman involved in a lot of charity work.

They decide to focus on Isaac and go undercover as Mapilla umbrella repairmen. While pretending to repair an umbrella, Vijayan's fake beard is discovered by a woman named Shobha. Suspecting them to be thieves, she raises the alarm but the duo escape. Vijayan and Dasan next dress up as parrot Tarot diviners. However, they are again discovered by Shobha, caught and taken to the police. Eventually, Shobha learns the truth about them and they become friendly.

Dasan and Vijayan tell their superiors and Prabhakaran that they know who the killer is and that they will make an arrest soon. This alarms Prabhakaran who sends masked men to attack them at home.

Vijayan goes undercover in disguise as a servant to Prabhakarans house which, coincidentally, is next to Isaac's house. Prabhakaran does not recognize him because of the disguise. At night, Vijayan sneaks out to get Isaac's blood but inhales chloroform accidentally and is unsuccessful. At midnight, a mysterious figure arrives at the house. This is Ananthan Nambiar, who is a close friend of Prabhakaran and who has broken out of jail. He seeks his help to get a fake passport so that he can leave the country. Nambiar is then sent to hide in his copra warehouse.

Dasan and Vijayan learn that Nambiar has broken out of jail and is searching for them. Both of them continue to try different ways of obtaining Isaac's blood but hilariously fail in their attempts. Isaac meanwhile suspects them as rival birdwatchers who have come to steal his research.

Prabhakaran restarts his drug smuggling operation. His lorry runs past a check point gate and the police chase them. Meanwhile, Dasan and Isaac end up in a tussle when the former tries to draw his blood while bird-watching. Dasan escapes in his Jeep. Isaac jumps into Thampi's lorry and throw out the men in it and follows Ramdas. Dasan's jeep gets damaged and he too jumps into the lorry. Isaac and he fight for control, but Dasan manages to escape with the lorry because Issac is distracted by the sound of the rare bullfinch that he has been looking for. The police are under the impression that Dasan has single-handedly overpowered the goons and seized the drug shipment.

Prabhakaran is shocked about the seizure of his shipment. Isaac and Prof. Vidyadharan go after the elusive bullfinch which was observed on an island and by chance, their boarding point is exactly where Gafoorka plans to rendezvous with Nambiar to take him to a different country. Dasan and Vijayan follow Issac and Viyadharan and run into Gafoorka and Nambiar. Nambiar jumps into the lagoon and escapes.

Nambiar informs Prabhakaran that the same CIDs who destroyed his smuggling business are the ones following him. They also see Isaac using binoculars and think that he works for the CIDs too. When they see Isaac leaving with a suitcase, they grab it from him thinking that it contains evidence against them.

Eventually, everyone including the CIDs arrive at the copra warehouse where there is huge free for all fight for the suitcase. Dasan and Vijayan realise that Prabhakaran and Nambiar are friends. They also realise that Isaac is a bird watcher. The police arrive and Prabhakaran, Nambiar and their gang are all captured. The Kerala government felicitate the CIDs for successfully solving the case
