Abby An and her parents are reborn ten days before the global zombie apocalypse, retaining painful memories of their previous death, betrayed by Chloe, Austin’s greedy gold-digger girlfriend. They cash out billions of fortune to refit a huge superyacht into an impregnable sea fortress equipped with high-voltage fences, greenhouses and heavy weapons. Liam, a former Navy SEAL who loves Abby deeply, brings his family to ally with them to stockpile supplies. When the zombie outbreak hits early, the group fights their way through ruined cities and subway tunnels, exposing Chloe’s infidelity and murderous schemes. It turns out Chloe also has rebirth memories and plots to seize all supplies. She steals lifeboat provisions and flees alone, only to be frozen solid by an unprecedented doomsday cold wave that wipes out most zombies. Trapped on the ice-locked ocean aboard their steel yacht, Abby, Liam, their families and fellow survivors stick together, holding on for the reconstruction of human civilization.
