In this series, Jack’s past is revealed and his son sets out to break the curse of Will, who became captain of the Dutchman at World’s End.
The key to breaking Will’s curse lies in Poseidon’s spear. He teams up with Jack and the scientist Carina on a journey to find it. There, a former captain of the Spanish Armada named Salazar, who had been under another curse, appears as a ghost. He had once been trapped for many years in a place called the Devil’s Triangle, having run aground by Jack’s clever steering while hunting pirates and chasing Jack’s ship. However, one thing led to another and they succeeded in escaping and attempted to take revenge on Jack. Jack and his friends search for Poseidon’s spear while running away from Salazar. And the spear was found at the bottom of the sea. The magic power of the sea splits the ocean in two, and Henry succeeds in destroying the spear, thus breaking Will’s curse and Salazar’s curse. But the curse is lifted and the sea gradually returns to normal, and they climb back onto the ship at anchor. However Karina is nearly caught by Salazar. Barbossa, holding a sword, comes down from above, stabs Salazar, and falls into the sea. Surprisingly,  Karina was Barbossa’s daughter. The death of Barbossa, who has been in the series since the first film, came as a great shock to fans. Later, Henry returned to land and finally meet with his father, Will, and then Elizabeth joined. It was a great scene for Pirates fans.
