In "One Piece" Episode 1089, the narrative unfolds with multiple storylines simultaneously. The episode begins on the Thousand Sunny, where the crew engages in a lively discussion about Luffy's dream. Jinbei finds the dream bold, Chopper is excited, Nami thinks it suits Luffy well, and Franky discusses the necessity of becoming the Pirate King. Robin points out the challenges in finding the last Road Poneglyph, which is essential for realizing Luffy's dream.

Elsewhere, at Marine Headquarters, a transmission from Sabo to the Revolutionary Army is intercepted. The Marines assume it is a distress call and attempt to trace the origin of the transmission.

Meanwhile, aboard the Big News Zeppelin, Morgans receives a series of sensational reports. These include the defeat of Kaido and Big Mom by the Worst Generation, the formation of the Cross Guild, and the attacks on Amazon Lily by the Marines and Blackbeard Pirates. Other news involves the Revolutionary Army's declaration of war against the World Nobles, the controversy surrounding Sabo—who is accused of murdering King Cobra—and the disappearance of Princess Vivi.

When the Five Elders intercept Sabo's transmission, they learn that he is on the island of Lulusia. This island becomes a focal point as King Seki and Princess Komane of Lulusia are captured upon returning from a world conference to their rebellious homeland. This turn of events makes Lulusia a strategic hideout for Sabo.

On Momoiro Island, Koala, Ivankov, and others celebrate the news of Sabo's safety. However, Belo Betty suspects there is more to Sabo's call. Sabo denies murdering King Cobra but admits to witnessing something disturbing in Mary Joa, which led to an assassination attempt on him.

Back on Lulusia Island, which is in the process of rebuilding after a pirate attack, dark clouds suddenly gather overhead. The imprisoned former King Seki faces the furious populace. Sabo is about to reveal crucial information about his discoveries in the Pangaea Castle near the Empty Throne, an allegedly forbidden area.

In Mary Joa, the Five Elders recognize the gravity of Sabo's revelations and cut off communications. They declare the day's discussions null and void and erase Lulusia's existence from their records. In a dramatic turn, the island of Lulusia is obliterated by massive laser beams from the sky.

Days later, aboard the Thousand Sunny, the crew navigates through a snowstorm. Jinbei skillfully maneuvers around icebergs, and Nami predicts the proximity of a winter island. Luffy, noticing an anomaly in the sea, encounters a warm mass of water. Zoro cools the water amid this chaos, and Luffy rescues Chopper from the storm. They encounter Jewelry Bonney in her child form, who warns of an impending monster threat. The episode culminates with the crew facing a giant sea monster that threatens the Thousand Sunny.
