Hunderby 1831. A young woman, thought to be a spinster missionary, is washed up on the beach... In an attempt to escape her terrible past, she assumes the name of Helene Blone (Alexandra Roach) and marries the local widowed pastor and master of Hunderby. Once wed, it soon becomes apparent that Pastor Edmund (Alex Macqueen), is not quite the man he appeared to be - and his peculiar housekeeper, Dorothy (Julia Davis), makes it clear she prefers the dead wife, doing all she can to undermine the new mistress. Such trials push Helene towards the sturdy arms of the dashing Doctor Foggerty (Rufus Jones). Can she resist his charms and birth her husband an heir to save Hunderby?
