Its summertime and Ammu has come to her Grandmother's once again, for the holidays. As always, the homecoming is a welcome change for the city bred Ammu and her doting Grandmother. As the estate car chugs along the rolling countryside, Grandma harks to the memory of a loss - it's been two years since Kamalam, Ammu's mother has passed away. Ever since, Ammu's father Sreedharan Menon has dutifully sent his little one to Grandma every summer for her vacations.

Once home, amid the sprawling familial mansion and its grounds, Ammu is wide-eyed and brimming with wonderment at the quaintness of country life and it's people - maids and neighbors gathered at gossip, the gawky but affectionate Thankachan, the caring Estate Manager Velayudhan Nair - above all, Grandma, tender yet strong in the conduct of affairs at the estate.

Grandma's fondness for Ammu finds depiction in the charming routines of simple country life - as they go a-picking dried leaves at the farm, washing at the pond by the house, the old woman sharing her understanding of nature, yet often hard put to answer Ammu's '…but Grandma why is it so?' questions. Grandma's recollections are suffused with melancholia as she recounts her childhood friends, the passing away of younger relations; and the Rose Apple tree at the farm that would no longer bear the fruit of its prime.

Amid the warmth Ammu's vacation draws to a close; it's time to get back to Calcutta, the city where her father works. Grandma is bereft of words, left pining for her little one. The parting has brought her back to the reality of a secluded life once again. For their next reunion, it would take another vacation, another summer.
