1913, shortly before the outbreak of WWI. A group of aristocrats gathers at the estate of Sir Randolph Nettleby for a weekend shoot. As the terminal decrepitude of a dying class is reflected in the social interactions and hypocrisy of its members, only world weary Sir Randolph seems to realise that the sun is setting.

When two mysterious deaths mar an otherwise pleasant weekend in the English countryside, unflappable flapper Lady Eileen Brent teams up with the dashing Jimmy Thesinger to solve the dastardly deeds. Their sleuthing leads them into a world of espionage and international intrigue as they discover a secret society known as "The Seven Dials" and the attempted theft of top-secret government documents.

Lawyer Wakem takes the mill on the river Floss away from Edward Tulliver (whose ancestors have owned it for 300 years) and becomes the worst enemy of Tulliver's family. When Edward's daughter, Maggie, grows up, she falls in love with Wakem's son Philip. However, her brother Tom (true to the memory of their father) forbids her to meet him again. When she visits her cousin Lucy Deane, Lucy's fiance, Stephen Guest, falls in love with Maggie at first sight, further complicating matters.

Hawk the Slayer, after seeing both his father and bride die at the hands of his malevolent brother, Voltan, sets out for revenge and the chance to live up to his title. Tooling himself up with the "mind-sword" and recruiting a motley band of warriors — a giant, a dwarf, a one-armed man with a machine-crossbow, and an elf with the fastest bow in the land — Hawk leads the battle against Voltan to free the land from the forces of evil and avenge his loved ones.
