Pirate Jean Lafitte declares was on Spain and raids Spanish ships under the Venezuelan flag, but never touches American ships. He fights the Indians and eventually establishes Galveston, on the Gulf of Mexico, where he hoards his loot. After one of Lafitte's pirates, unordered, sinks an American ship, he is hanged. Belle Summers intends to find out whether Lafitte was guilty and although she finds the truth, her servant betrays her and the American Army moves into Galveston, destroying the pirate's headquarters, while Lafitte and Belle make their escape.
