It is 1995. Tara Taneja lives in the small town of Siyaka, running Ultimate Mathematics Tuition Centre and working for Lalaji, her grandfather, at Lallan Sweets, his famous sweet shop. The laddoos sold at the shop are made using a secret family recipe that contains a magic ingredient known only to Lalaji.
When Lalaji chooses to retire, he decides that Lallan Sweets will not be inherited but earned. He devises a quest for his three grandchildren-Tara, Rohit and Mohit-to discover the magic ingredient. Whoever finds it first will get to run the shop.
It helps that Tara’s long-time crush and neighbour, fun-loving and good-natured Nikku Sabharwal, returns to Siyaka after years. He joins Tara in her pursuit to outsmart her cousins. As the quest takes them from Mathura to Ludhiana, they must battle old secrets, family legacies and unexpected dangers. Yet, the toughest part will be acknowledging their feelings for each other. Will this journey bring them together or lead to a bittersweet end?
