Contemporary London. Detectives Robert Hicks and Elaine Renko are both partners and enemies as they strive to uphold the law and protect their loved ones in a world that is sliding daily towards certain doom. Hicks is a family man and a good dedicated detective, but also extremely corrupt. Renko is troublesome and damaged, but an absolutely incorruptible and honest detective. Even though the two differ across the moral and social spectrum and really cannot trust each other, they will have to learn to work together if they are to survive the end of the world.
