What it's about: The sci-fi series loosely follows the events in Justin Cronin's novel of the same name, which tracks the evolution of a virus that essentially turns its victims into vampires, and the one young girl who could be the key to saving everyone. Mark-Paul Gosselaar stars as the federal agent tasked with tracking her down (and who later decides to protect her, instead), while talented young actress Saniyya Sidney (Fast Color) portrays Amy.
