At the end of the world, the undead aren’t the greatest threat to those who have survived. A deadly plague brought on by an experimental AIDS drug called Lazarus sweeps the country. Lazarus, named so because it brings patients back from the brink of death, has the unfortunate side effect of bringing the dead back to life. A handful of survivors have made their way to water where the walking dead–called ‘sinkers’–are less of a threat. These battered and traumatized survivors have colonized a super yacht (Flyboy), a tugboat (Big Daddy), and a weekender yacht (Barbra’s Bay Breeze). As they wait for more survivors and organize a voyage south to a warm climate, they unintentionally bring aboard a monster who might be the end to them all.
