25 parts Ongoing What was supposed to be a dream vacation turns into a nightmare. A group of elite high school students embarks on a luxury cruise for their graduation trip, unaware that a deadly virus has been secretly transported on board. When the infection breaks out, the ship becomes a floating graveyard-trapped in the middle of the ocean with no way to escape.
As the virus spreads, turning students and crew into bloodthirsty monsters, [Female Lead], a fearless scholarship student, finds herself leading a fight for survival. She clashes with [Male Lead], a wealthy and strategic student hiding a shocking secret. Meanwhile, power-hungry survivors form factions, making the humans just as dangerous as the infected.
With the ship slowly sinking and the infected evolving, the survivors must uncover the truth behind the virus-before the ocean swallows them all.
Will they find a way to escape, or will they become part of the deadly dawn?
