The Bajoria family was large but their house wasn't big enough to accommodate everyone. After the heads of the family, brothers Radheshyam and Anand, lose their legs in an accident, all hell breaks loose. The family-of-15 begins to crack as the brothers' children start bickering constantly.

As a young and handsome Ayushman lands in Kolkata from Singapore, he quickly learns that he isn't the only architect in line for the project. That's when he convinces his two best friends, Biswajeet and Jackie, to join him on an adventure of building an architectural marvel and exploring the riches of West Bengal.

Who finally gets to make a billionaire's house? The three carefree and youthful boys or the architect tycoon Mittal, who's as sleazy as they come?
