“NOTHING is going to save our lives – we are breathing borrowed air,” the cynical Will tells the optimistic but overly obsessive Stella in this latest disease-of-the-week film.

Both have cystic fibrosis (CF), meaning that they have to remain physically apart to prevent Will from giving her a killer bacteria. As you watch their love blossom after a prickly start, it is heartbreaking when they can’t do the things we all take for granted such as holding hands, touching, hugging and kissing.

In an act of rebellion, Stella, with the aid of a snooker cue, agrees that they should stand five feet apart.
