Hari, a government employee, lives with his wife Sujata, their son Sankaran, and his brother Murali. When Hari's colleague Reji and his family visit for two days, the families celebrate, despite Murali being tired from work. The next day, Hari and Reji attend a wedding with their wives, leaving the children—Helen, Maria, and Sankaran—at home. Maria invites Sankaran to play a game, but as they play, the mood and intensity of the game shift dramatically.
