Aisha is born with a rare disorder, severe combined immunodeficiency or SCID, which infants rarely survive because their immune system isn't developed enough to combat even common infections. Aditi and Niren, who have lost another child to the same affliction, take her to London for an experimental treatment, raising the funds required, a hefty amount, thanks to a desi talk show appeal. After that is the story of Aisha's survival, as she almost turns into a Bubble Girl, cocooned from the world without. A byproduct of that treatment is lung disease that ultimately causes her demise, but not before she has enjoyed much more life and even delivered to book on her experience.
