It is 1841. Patty Clare is married to John Clare: peasant poet, genius and madman. Travelling home one day, Patty is shocked to find her husband sitting at the side of the road, having absconded from a lunatic asylum. Delighted to see him, she is devastated when it becomes clear that John's mental health has deteriorated, and he now thinks himself married twice: to both Patty and his childhood sweetheart. Patty still loves John deeply but he seems lost to her, obsessed with the idealised memory of another woman. She finds herself consumed with jealousy and struggling to cope with her unruly family. Will she ever be able to conquer her own anger and hurt and reconcile with this man she now barely knows?
