When Gilbert Williams, a resident at Sunset House Care Home, claims to have once killed someone, care assistant Will Cavanagh initially dismisses his claims – he's frail and vulnerable, he can't imagine him ever killing someone – but he can't seem to let his comments go. What if it's true? What if he really did kill someone and he's forgotten that he isn't supposed to tell anybody...
