Zor Lagaa Ke Haiya is a heartwarming tale of four kids—Laddu, Priya, Ritesh, and Karan—who live in the same building and feel threatened by a beggar they nickname Ravan due to his scary appearance. Intrigued by the bag he always carries, they try various plans to steal it, but Ravan outsmarts them every time. They decide to build a tree house in their building compound to keep watch on him. Ram, a laborer, helps them construct it. After several attempts, the kids befriend Ravan, and the tree house becomes his night shelter. Danger arrives when ruthless builder Bakshi plans to cut down the tree for a new gate, aided by contractor Gupta. The kids, with Ravan’s help, fight to save their tree.
