Mina can't wait to celebrate Holi, the high-spirited Hindu spring festival of colour. Every year she and her family have a party and Mina invites all of her classmates. But this year it will be different because Mina's Nanaji (grandfather) is now living with the family. Mina has not adjusted to this addition to the household and is confused by her embarrassment of Nanaji's continuous advice and thick accent. But when Mina overhears a new classmate making fun of the way Nanaji talks, she is horrified and begins plotting the perfect revenge. The Holi celebration soon loses its carefree, joyful atmosphere as Mina worries about her payback. But before she is able to ruin the party for herself and her classmates, Nanaji reminds her of the true spirit of Holi, allowing Mina to come to terms with her true feelings about her family.
