In order to fulfill his older brother's dream of aging their whisky in sherry barrels, Payton King undertakes a perilous journey to war-torn Spain. He must outwit Napoleon's troops and retrieve special barrels sent to Spain years before. His only hope of success lies in reliance on a band of Spanish partisans who are bravely determined to oust the French from their country.

Along with her father, Alba Castillero joins the guerrilla fighters after their sherry bodega is sacked and her mother murdered by French soldiers. She is drawn to Payton but knows he is promised to an Englishwoman back home.

Things become more complicated when Alba's father begs Payton to take her to safety when he sails away from Spain.
