Spring 1810. Young Parson Tobias Campion is excited to be taking over the small Warwickshire parish of Moreton Priory. But his first night in the village brings excitement of the wrong kind when Tobias intervenes in an attempted rape and becomes hero to housemaid Lizzie Woodman.

As Tobias settles into life in Morton Priory he finds friendship in the form of Dr. Edmund Hansard and his concern for Lizzie quickly blossoms into something more. But as Jem, Tobias's groom, and local farm boy Matthew compete for Lizzie's attention Tobias resigns himself to the fact that his feeling for the girl will remain unrequited. Soon, however, his mind turns to other matters when the unsettling death of poverty stricken poacher Mr Jenkins, the suspicious demise of local aristocrat Lord Elham and a mysterious attack on Tobias himself make one thing clear; a malign influence is at work in the supposedly sleepy hamlet!
