Both live in fear of Uncle Frank Stinson (Sean Bean), who runs the illegal family business with an iron fist, aided by his psychotic younger brother Bobby. But when Amber falls in love with family rival Wild Bill (James Purefoy), Hannah realizes there is no escape from the ruthless Stinsons, and cleverly schemes to pit one pawn against another in a cunning game of revenge.
Immediately after the events of The Desolation of Smaug, Bilbo and the dwarves try to defend Erebor's mountain of treasure from others who claim it: the men of the ruined Laketown and the elves of Mirkwood.
