A dream sailing expedition across the Pacific transforms into a claustrophobic nightmare when a crew member vanishes overboard, forcing the remaining passengers to confront the dark histories they attempted to leave behind. Lana and Kitty, seeking liberation from their mundane lives, secure passage on a fifty-foot yacht named The Blue, only to find that the vessel serves as a sanctuary for individuals harboring dangerous secrets. As the yacht navigates the vast, isolating expanse of the ocean, the initial camaraderie dissolves into suspicion and paranoia. The narrative, told through a lens of mounting dread, tracks the protagonists as they realize their fellow travelers are not who they claim to be, turning their idyllic escape into a desperate struggle for survival against both the elements and their companions.
