A group of 15-year-old boys live in a very peculiar "block": the orthopedic ward of a children's hospital, where the patients have various forms of cancer. Armed with irrepressible good cheer and a tenacious desire to live their lives fully, Miguel Angel, Izán, Dani and Jorge defy destiny and carry on as if this microworld ruled by men and women in white coats was a thoroughly normal environment for adolescent boys. Besides their high-sodium drinks, there are always new patients to meet, nurses to play jokes on, nightly excursions through the hospital corridors, basketball games against the team from St. Paul's. Friendship and group acceptance are important at their age, but they are absolutely essential when you are spending your life in pyjamas between four walls. Still, this doesn't mean that you've given up your individual identity. Each has his personal problems and his own way of dealing with them -- Miguel Angel's desire to be seen self-sufficient, Jorge's fear of an upcoming diagnosis, Izán's haunted memories, Dani's first encounter with love. But the environment for these fears and hopes is always the same and while it is a world with its own traditions, hierarchy and slang, it is still part of the real, larger world that encompasses the hospital.
