June moves into the cardio-pulmonary unit and dies of a myocardial infarction. She ends up in the morgue, where she donates her organs. Her lungs are harvested for transplant—strong and healthy after breathing years of oxygenated hospital air. The recipient, a young man with emphysema, takes her lungs outside St. Joseph's for the first time in sixty years to breathe the fresh Los Angeles air.
June's delicate hospital-air spoiled lungs can not be expected to take on the heavy reality of city air, added to now by years of accumulating pollution, and the young man doesn't survive long.
