The Parson of the title is not a cleric, but an upright young army officer so nick-named for his apparent prudishness. On leave in his native homeland, he meets a rich and beguiling beauty, the woman of his dreams. The days that the Parson spends with Rejane, riding in and exploring the wild moorland have their own enchantment. But Rejane grows restless in this desolate land; doubtless in love with the Parson, she discourages any intimacy. Until that is, she persuades him to take her to a sinister castle situated on a treacherous headland.
