The aged couple, Marykkutty teacher and Narayanan who has fully succumbed to the Alzheimer’s disease are all set to fly to the US to visit their relative there. The sudden floods that submerged the roads force them to return home from on their travel to the airport. They reach back home past midnight and amidst heavy downpour oblivious even to their immediate neighbours. To her awe, Marykkutty sees that the flood water is aggressing inside into their house and the water level is on a steady rise. The mobile telephone lines are dead and the power supply is also cut that the poor old lady is deprived of all chances to reach out to the world outside for help.
