Sex means death in this teen romance which doubles as a disease awareness-raising drama.

Haley Lu Richardson and Cole Sprouse are a sweetly charming photogenic pair of patients, who meet in hospital while undergoing treatment for cystic fibrosis.

There is no cure for the genetic lung disorder which considerably shortens life expectancy. Five feet is the distance they must keep apart to minimise risk of a potentially fatal cross-infection, and touching and kissing are forbidden.

There are shades of the vampire Twilight series in their forced abstinence of contact, as well as noticeable nods to Kate Winslet’s epic romance in Titanic.

Based on the novel by Rachael Lippincott and dedicated to campaigner, Claire Wineland, it touches briefly on the financial cost of treatment and thankfully keeps the vomiting and other side effects down to a manageable degree.

If a little too much of the dialogue sounds like a teenage inspirational instagram post, then at least the film knows its target audience.
