So when the story opens Babu is a school going boy (This role is performed by Kamal Hassan). Mohan goes abroad on an official assignment and Babu is enrolled in a boarding school. Babu becomes lonely and homesick especially when he sees his classmates getting letters from their parents and when they come to meet them. Babu is made to believe by the old servant that his mother is in 'vaikuntam' (heaven). Babu sends letters to his mother addressed as "Mother, Vaikuntam". The letters are entrusted to the gardener Gopalan Nair (Muthukulam Raghavan Pillai) to be mailed. Gopalan Nair's daughter Sarala (Ambika Sukumaran) happens to see the letters. She takes pity on the child and replies to the letters as if sent by his mother whom he believes is in heaven. Through these letters, Sarala and Babu become close to each other
