The story begins at Tahasildar Rameshan Nair's home. His wife Arundathi and children prepare to celebrate Thrikarthika. His daughter Arathi, lovingly called Ammu, has not returned from office yet.

Ammu tells her mother and father of the accident and how she admitted Mr. Unni Ravi Varma to the hospital. Her parents are shocked by the mention of this man's name.

A grateful Unni Ravi Varma tries to thank Ammu. However, his generosity is not accepted by her parents. They never expected to have him enter their life again. Arundathi does not approve of Ammu's decision to visit Unni at the hospital.

Arundathi, Ammu and Nandhu receive anonymous messages that Ramesh's life is in danger. There is also an attempt at kidnapping Gopika. Ramesh assumes Jagadheeshwaravarma is behind this and confronts him.

Karthik's mother approaches Ammu with a marriage proposal. She later calls and speaks to Rameshan about this.

Karthik and his mother arrive at Rameshan's for the Pennukaanal. Before he leaves, Ammu tells him that she has something to say to him.
