Netflix released the official teaser forThe Sea Beaston July 03, 2025, and released theofficial traileron July 10, 2025. The trailer introduces us to Maisie Brumble, who’s reading a book that talks about a time when sea beasts used to torment the lands and the seas and nobody was safe. Maisie meets Jacob and she is very impressed with his accomplishments and tells him she wants to join his crew. Of course, Jacob isn’t going to let a child on the ship and sends her off but, when he gets on the ship with his crew to go kill monsters, he realizes that she stowed away.
Jacob plans to drop Maisie off at the nearest port but she’s resilient. She points out that he joined the ship when he was her age and look how he turned out. Her similarities to him are also pointed out by another crew member who tells Jacob that he sees the same fire in her that he once saw in him (Jacob). While this is going on, a large sea monster is plaguing the ship and Jacob is trying to fight it off. Meanwhile, it seems Maisie has a different view of monsters and even tells Jacob that just because he’s a hero doesn’t mean his approach isn’t wrong.
