Once Meenakshi's family finds out about her love for Unni and they visit his house for a marriage request. But Unni has a past he can't escape, which he narrates his flashback to Meenakshi.

He fell in love with a woman named Aswathy, a medical student. Aswathy's parents are dead, and she lives with her uncles Karimparakal Prabhakaran, Sudhakaran and Divakaran and their family.
