Josie Long presents a selection of short documentaries about communication - messages that could break your heart, rescue you from a fight or save you from a long stay in jail.

The writer Glenn Patterson explains why sometimes we should ignore the writing on the wall, and musician Tom Robinson describes the unlikely message he sent at a time when he was in a lot of trouble.

Stories of last words, lost love and lights being knocked out.
