The Xanthakos family's voyage from South Carolina turns ugly when the ship's captain maroons Lilyan and her family on an island along North Carolina's Outer Banks. There, the family is captured by pirates and taken to a secret island hideout where they witness a mock trial and a hanging.
Forced to rebuff the advances of the murderous pirate, Captain Galeo (The Shark), and fearful that her children will be auctioned off to the highest bidder, Lilyan forges an escape plan. Meanwhile, her husband, Nicholas, calls upon his skills as a captain in Brigadier General Francis Marion's militia to devise a battle plan to save his family.
Will the young couple's faith be enough to see them through? Or will their declaration to rescue the infant slave girl, Cassia, from the pirates prove too high a price?
