Everyone has a Tully Dawson: the friend who defines your life.

In the summer of 1986, in a small Scottish town, James and Tully ignite a brilliant friendship based on music, films and the rebel spirit. With school over and the locked world of their fathers before them, they rush towards the climax of their youth: a magical weekend in Manchester, the epicentre of everything that inspires them in working-class Britain. There, against the greatest soundtrack ever recorded, a vow is made: to go at life differently.

Thirty years on, half a life away, the phone rings. Tully has news--news that forces the life-long friends to confront their own mortality head-on. What follows is an incredibly moving examination of the responsibilities and obligations we have to those we love. Mayflies is at once a finely-tuned drama about the delicacy and impermanence of human connection and an urgent inquiry into some of the most important questions of all: Who are we? What do we owe to our friends? And what does it mean to love another person amidst tragedy?
