Madeline Whittier is an 18 year old teenager with illness SCID which means she is allergic to everything. She has been living in her LA home for seventeen years behind contaminated walls.
A family moves in next-door to Madeline and she falls in love with their son named Olly. They begin text messaging online as their rooms are across each other. One day, Carla (her nurse) sneaks Olly into the house and they meet.
Dear Ms. Whittier, the results have drawn us upon informing you that you are not diagnosed with SCID. From, Hawaiian Hospital
Madeline and Olly decide to travel to Hawaii because they want to spend some time together. They explore the place and have an enjoyable time.
I can't believe you mom!
Madeline gets extremely sick because her body is only used to the environment she lives in and therefore; ends up in the hospital.
After they return, Madeline gets a letter from the doctor who treated her in Hawaii saying that she doesn't have SCID and got sick because she spent her whole life inside and has never formed a natural immunity.
Madeline's mom only told her that she had SCID to protect her as she was her only one left after the death of her husband and son. Madeline runs away and Olly moves out however; they reunite in New York.
