Miss Milly, a pretty young newcomer to North Fork, buys the General store and immediately antagonizes all her customers, including Lucas, by demanding that they pay up their back accounts before she'll extend any more credit. When a fast-talking con man persuades Milly to hire him and his gunman partner as "collections" agents, she agrees, not knowing that the collection methods include a gunfight when the con man nearly kills a neighboring rancher and then threatens Lucas.
