While in Camp Half-Blood, Percy recounts the story of Thalia and her sacrifice. A young Annabeth, Luke, Grover and Thalia are running to Camp Half-Blood while being pursued by monsters. Thalia sacrifices herself to get the others into the camp, and her father Zeus transforms her into a pine tree, creating a magical border around the camp. Soon a Cyclops passes through the border and is revealed to be Tyson, Percy's half-brother. The camp is later attacked by a Colchis Bull who breaks through the border and ravages Camp Half-Blood. Percy defeats it with the help of Tyson, Annabeth, and Clarisse. Following this, Luke (who had survived his and Percy's battle in the previous film) appears and confronts Percy, trying to convert him to his cause. When Percy refuses, Luke disappears.
The campers realize that Thalia's tree has been poisoned by Luke and they are vulnerable to attacks. Percy visits the Oracle, who tells him of a prophecy of a half-blood of the eldest gods either saving or destroying Olympus. Chiron tells Percy that he is the only living, human half-blood of the eldest gods, so the half-blood in the Prophecy may refer to him. Annabeth and Grover learn about the Golden Fleece, which has the power to heal anything, and propose a quest in which they retrieve the Fleece and use it to heal Thalia's tree. Mr. D chooses Clarisse to lead the quest, much to Annabeth's and Percy's dismay. Percy convinces Grover and Annabeth to accompany him on the quest, and Tyson joins them. Annabeth hails the Chariot of Damnation, and Percy threatens the three drivers (the Graeae) to tell him of his prophecy, giving him coordinates for the Sea of Monsters (the Bermuda Triangle) before ejecting the group from the cab in Washington D.C. because they lack money. While walking down the street, Grover is kidnapped by Chris Rodriguez and taken to Luke. Percy, Annabeth, and Tyson first locate Luke with the help of Hermes, then ride a Hippokampos to his yacht, the Andromeda. Luke reveals his plan to revive Kronos using the Fleece so Olympus will be destroyed. Percy and they are then locked in the brig, though they later escape when Percy uses his ability to manipulate water.
The group is consumed by Charybdis, and they discover Clarisse in the monster's stomach. Percy and Clarisse work together to escape Charybdis by shooting a hole through its gut, and soon they arrive at Circeland, Polyphemus's lair. Percy finds Grover, and the five escape Polyphemus, retrieving the fleece and trapping him in his cave. Afterwards, Luke arrives and demands the fleece from Percy, who refuses. Luke shoots a crossbow bolt at Percy, but Tyson takes the bolt in the chest and falls into the water below.
Luke begins reviving Kronos and Annabeth encourages Percy to take leadership. The team escapes captivity, and Percy grapples with Luke over the Fleece, like the prophecy said they would, but Luke easily gains the upper hand. Luke is suddenly thrown away by Tyson, revealed to have survived his wound due to the water healing it, as he is Poseidon's son. Kronos rises from the sarcophagus and consumes Luke and Grover before battling Percy. Percy realizes that Riptide is the "cursed blade" of the prophecy and slices Kronos into pieces imprisoning Kronos in the sarcophagus once again, causing him to regurgitate Grover and Luke, the latter landing in Polyphemus's Lair. Their victory is short lived as Annabeth is stabbed by the Manticore, who is killed in turn by Clarisse and Grover. Annabeth dies in Percy's arms but is resurrected by the Fleece. Percy then gives the fleece to Clarisse, and they return to Camp Half-Blood. Clarisse places the fleece on Thalia's tree. The group returns the next day to find Thalia alive, as the fleece returned her to human form.
Percy realizes that Thalia, as a child of Zeus, is another possible child of the prophecy about either preserving or destroying Olympus. The film ends showing the sarcophagus with Kronos's remains in it glowing, implying that Kronos still has some degree of his power, and is still planning to return.Logan Lerman as Percy Jackson, the demigod son of Poseidon.

The film received mixed reviews. The review aggregator website Rotten Tomatoes reported a 41% approval rating with an average rating of 5.1/10 based on 111 reviews. The website's consensus reads, "It's pretty and packed with action; unfortunately, Percy Jackson: Sea of Monsters is also waterlogged with characters and plots that can't help but feel derivative." On Metacritic, which assigns a normalized rating out of 100 based on reviews from critics, the film has a score of 39 based on 33 collected reviews, indicating "generally unfavorable reviews".
Jim Vejvoda of IGN rated the movie as 6.0 out of 10, awarding "There are worse sequels than the CG-heavy Percy Jackson: Sea of Monsters, but it's just such overly familiar territory." Gary Goldstein from Los Angeles Times gave the film a positive review, saying that "tweens and young teens should be sufficiently distracted by the movie's brisk pace and heroic mayhem — if they're not too unnerved by its at times nightmarish imagery", while James Rocchi from ScreenCrush said "Percy Jackson: Sea of Monsters is hardly the stuff of legend, but by keeping the plot straightforward and the storytelling clean, it's an odyssey the intended young audience will be glad to take." Marsha McCreadie on Roger Ebert's website gave the movie two and a half stars out of four and called it "a gentler-spirited, less flashy enterprise, though it still presents a natural world that can morph at the whim of a god."
New York Times writer Andy Webster states, "Sea of Monsters is diverting enough — the director, Thor Freudenthal is savvy with effects and keeps his young cast on point — but it doesn’t begin to approach the biting adolescent tension of the Harry Potter movies." In a negative review, Michael Rechtshaffen of The Hollywood Reporter posted as the bottom line that "Buoyant effects help keep this sequel from being a noisily hit and myth proposition." Bruce Ingram of Chicago Sun-Times thought the movie had a "deficit of thrills" and "faithful fans of the novels will be unhappy with the liberties taken with the adaptation like they were with the first film." Some critics were merciless, like Josh Bell of Las Vegas Weekly who called the series "a thoroughly second-rate franchise" and said "with movies like Sea of Monsters, it can probably continue in acceptable mediocrity for years to come" and Connie Ogle of The Miami Herald who says "In Percy Jackson: Sea of Monsters, choosing the dumbest character is a colossal task."

At the 2015 Santa Barbara International Film Festival, Lerman said that while he finds the Percy Jackson films fun to make, he has not heard anything about the production of a third film and expressed concern that he and his co-stars were growing too old for their parts.
