Dasan notices Isaac and begins to watch him. At that time, Vijayan arrives there with tea. He also tries to look but ends up dropping the tea. The tea falls over Thampi who beats him and calls him a rascal. Vijayan comes back from Thampi's house, finds someone wearing the mask of the murderer and beats him. Dasan arrives, catches Vijayan and saves Damu who had been wearing the mask. Damu criticizes them for not finding any proof for the investigation. Vijayan shouts at Dasan for his lack of support at Prabhakaran Thampi's house. Vijayan tells Ramdas that he is going back to Madras (Chennai). Ramdas reveals to Vijayan that Ananthan Nambiar has broken out of jail and is searching for them. At that time, the phone rings and CI tells them that the Home minister is waiting for them. They arrive at a guest house. The Home minister asks them about their developments in the investigation. They tell him that they are observing the suspect from a distance. The Home minister criticizes them for not having carried out a proper investigation and threatens to have them cashiered should they will fail. Ramdas retorts to the Home Minister that he has also got a bone to pick about the treatment of SI Rajendran following his accident and reluctance of Govt. to give the job to his widow Shobha. He suggests that the Home Minister should first try to get her job and then criticize the investigation. They leave there in a huff. Ramdas relates to Shobha all that has happened. Vijayan doubts Dasan and teases that he has fallen for Shobha. Dasan retaliates by taunting Vijayan for failing to obtain Isaac's blood. Ramdas challenges Vijayan and states that he will bring Isaac's blood without his help. Dasan arrives at a hotel where Isaac and Prof. Vidyadharan have gone for lunch. Dasan tries to get Isaac's blood using a syringe, but manage to get only the waiter. Isaac tries to catch him but he escapes from there. Isaac recognizes Dasan, who has been following. He suspects that he came to steal his experimental details of bird watching. Prabhakaran Thampi arrives at the copra warehouse and tells his man to start the drug-running from Idukki. His lorry rams down a check post gate and the police chase them. Meanwhile, Dasan tries to draw Isaac's blood when he is engaged in bird watching.
