I give this movie 4/5 its a pretty good American romantic drama film. There were two young patients with cystic fibrosis one male and one female and they fell in love with each other but they can't be closer than 5 feet together because they could get each other sick... They made a 5 foot stick that they held so that they could still talk with one another but not get sick. They then got into some trouble while they were walking and the boy had to do mouth to mouth because she was drowning and they surprisingly she didnt get sick from him...
