Not enough people give blood - those who do are valued and appreciated.

This film says ‘thank you’ to donors in waiting rooms all over the country, while they’re having a cup of tea and a jammy dodger. It plays on a loop and is subtitled (so that it works with the sound down).

There are facts and figures, whys and wherefores – but the most resonating expressions of gratitude come from recipients who wouldn’t be here if it weren’t for the people watching the film.
