Mariamma is a post-graduate in Economics and talks to the walls, the consequence of a childhood tragedy. They have two sons. Unni Chacko and Thoma Chacko. Unni is adored by everyone and is an awesome cartoonist. Thoma who is the youngest son and is an adolescent is always anxious about things and is terrified of everything. While everyone in the neighbourhood is busy racking their brains preparing for IIT, Unni is least affected by this mania for academic excellence.
