Reasonably comfortable with his possession of wealth, Monk moseys through his days taking care of his grandkids. After a car accident takes out his beloved Falcon and leaves him injured, he begins to see that many of the people around him are on edge. His wife, Agnes, no longer has a job and is working through parental issues with her father.
Meanwhile, a book given to him in jest, may in fact be a primer for the disaffected rich to move the country away from democracy to autocracy by whatever means, including violence. Monk thinks this is silly until people connected to the book start dying. Foolishly drawn into this scheme, along with Agnes' sudden interest in sleuthing, Monk finds that they are now targets themselves, and decide to play along to learn more, even if it leads them to their possible demise.
