Synopsis

Bullied student Alia boards a Halloween cruise, only to find her classmates dying—and coming back as zombies. Her only guide is Adrian, a mysterious man no one else can see, who reveals the ship is actually a giant sacrificial altar. But the biggest secret isn’t the ship—it’s Alia herself: she’s Persephone reborn, and Adrian has been waiting lifetimes for his Queen.
