"You've endangered us. You've endangered your family." During an attack on London, 20 year old Imogen joins a campaign offering refuge to victims. Before her family have even had a chance to have a reasonable discussion, John is at their door. He is different to them. He isn't what they expected. And although they'd never admit it to themselves, he isn't necessarily what they want. "You will do anything, in the end, to keep the people you love safe." One for Sorrow is Cordelia Lynn's second play to have its world premiere at London's Royal Court Theatre, following her acclaimed debut Lela & Co.
