The series follows Jassie Singh, a young woman from a small town with big dreams who, rebelling against her strict father, decides to leave the military base in Karnal where she grew up and moves to Mumbai. She accepts a job as a nanny and moves into a multimillion-dollar penthouse with the wealthy Malhotra family which includes jet-setting parents Rahul and Riesha Malhotra and their four rambunctious children: Ayesha, Rocky, Subbu, and Tia, along with the family pet, Shri Premchand, a seven-foot Asian water monitor lizard, that was later revealed to be a female. With a whole new world of experiences open to her, Jassie embarks on new adventures in the big city as she grows to rely on the love and support of the children in her care. Assisting her are Tony (Kenneth Desai), the family's lazy and sarcastic butler, and Lucky (Devansh Doshi), the building's 20-year-old receptionist.
