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, 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 they make a vow to go at life differently.
Thirty years on, half a life away, the phone rings and Tully has news. Mayflies is a memorial to youth’s euphorias and to everyday tragedy.
