Plot
(From Wikipedia)
In 1665, Captain Charles Hunter is hired by the Governor of Jamaica, Sir James Almont, to lead an expedition to the island fortress of Matanceros. It is there that a galleon, supposedly containing treasures untold, is awaiting protection across the Atlantic for safe travel back to Spain. Almont is excited about the possibility of reward in this venture, though his secretary Mr. Robert Hacklett is less than enthusiastic, calling Hunter a pirate.
Hunter gathers his crew in Port Royal and sets sail to capture the ship in its own harbor. Mere days into the journey, their ship, the Cassandra is captured by a Spanish Warship commanded by none other than Cazalla, the infamous Spaniard who commands Matanceros. After a daring escape from their cell, Hunter and his crew reboard their ship and continue on their way before Cazalla can retaliate.
Upon their arrival at Matanceros, Hunter, Black Eye, Lazue, Sanson, and the Moor all make their way behind the fortress. Traversing up skyward cliffs, rough jungle foliage, and deadly animals, the crew comes to see that Cazalla has docked under the suspicion that Hunter is still on his way to the island. The privateers manage to make their way around the village and soldiers occupying it long enough to set their traps. After a short duel between Hunter and Cazalla, the traps are sprung, and a slice to the throat kills Cazalla. The Cassandra appears and the crew takes their captain, his mates, and the galleon out to sea.
After a few days, the treasure inside the galleon, El Trinidad, is accounted and split between the two ships. Soon afterward, Hunter discovers he is being pursued by the warship commanded by Bosquet, Cazalla's second-in-command. He is chased to Monkey Bay, where he narrowly evades capture with the aide of Lazue's eyesight. The warship is unable to follow due to the sun's glare on the ocean. Here Hunter waits until a few days later, the crew notices the signs of a terrible storm: a hurricane. Using the genius of Don Diego, their cannons are armed and aimed for a mere two defensive shots. Upon their departure, however, the warship has disappeared.
Celebrating their surprise escape, a few miles out to sea, the warship is seen coming on their stern quickly. With Hunter aboard El Trinidad, the ship took massive damage from cannon fire until the two were in perfect alignment. The aimed cannons fired upon the warship, merely damaging it with the first shot and seeming to miss entirely on the second. However, after a moment of inactivity, Hunter realizes that the second shot actually landed a devastating blow and the attacking ship explodes with geysers of water shooting into the air. Moments later, there is little evidence of the warship.
Victory evades the two ships, however, as it begins to rain and storm. The El Trinidad and the Cassandra, helmed by Sanson, are separated by fierce winds and strong currents. After the storm abates, Hunter finds the El Trinidad beached on a strange island. A few hours later, they see the island is inhabited by cannibalistic natives, who nearly capture the niece of Governor Almont. On their way back to Port Royal, the crew suffers yet another misfortune when their ship is attacked by a Kraken. After it had killed many and damaged the ship, Hunter manages to mortally injure the beast. Their path is finally clear to Port Royal.
Upon their arrival, a courier gives message that Almont is gravely sick and Hacklett has taken charge as Governor. Hunter is arrested and put to trial, with Sanson betraying his captain and lying for the court. Hunter is sentenced to be hanged and placed in prison. With the aid of the sickly James Almont, Hunter is sprung from prison and kills the men who sentenced him, save for the judge himself who gives Hunter a pardon. Hacklett is shot in the groin, and Sanson sends word that he alone knows where the other half of the treasure is. Hunter turns the man's own crossbow against him and kills Sanson and throws his body overboard letting the sharks eat his body, yet is never able to find Sanson's treasure.
