Capt. Jack (Johnny Depp), swallowed by a giant octopus, enters the "dead world" controlled by David Jones-the end of the world. In order to save Jack, Will Turner (Orlando Bloom), Elizabeth (Keira Knightley), and the witch also came to the "dead world". After finding Jack, they untied the spell and escaped the end of the world. At this time, the cunning Cutler Beckett (Tom Holland) had already obtained the heart of David Jones (Bill Nye), so he held David Jones hostage, controlled all high seas pirates, and gained benefits for the East India Company. In response to the crisis, pirate leaders from all over the country gathered secretly to debate whether to release the female sea god and kill David Jones. It turned out that the female sea goddess was David Jones's old lover, and the delicate relationship between the two became the key to the confrontation between the two sides. On the calm sea, wind and rain are coming, and the final showdown is about to begin. What fate does everyone face? When the final trial is over, can the sea return to its former tranquility?
