Basha and Sainabi are in a panic. Ammi is ill, and Saira aunty has just announced that she is arriving for lunch - with 23 other people! Budding chef Basha thinks he can cook Ammi's Dum Biryani, but her recipe only makes enough for 4 people. Math wiz Sainabi jumps in to help, declaring that she knows how to turn a 4-person recipe to a 24-person recipe. Do the siblings succeed in serving up a truly Dum Dum-a-Dum biryani?
