It is 1841. Patty is married to John Clare: peasant poet, genius and madman. Travelling home one day, Patty finds her husband sitting, footsore, at the side of the road, having absconded from a lunatic asylum over eighty miles away. She is devastated to discover that he has not returned home to find her, but to search for his childhood sweetheart, Mary Joyce, to whom he believes he is married. Patty loves John deeply, but he seems lost to her. Plagued by jealousy, she seeks strength in memories: their whirlwind courtship, the poems John wrote for her, their shared affinity for the land. But as John descends further into delusion, hope seems to be fading. Will she ever be able to conquer her own anger and hurt, and reconcile with this man she now barely knows?
