Rose Baker is both shocked and infuriated to find out that her brother Judd has been the ringleader of a conspiracy to promote political assassinations over the years. These assassinations were of Rose's political idols. In the violent argument that ensues, Judd falls and is fatally injured. Certain that his dozen co-conspirators will never face the justice they deserve, she hatches a plan to make sure that they do. Traveling the four corners of the country, she takes them out one by one. Always a step ahead of the conspirators and the authorities who would never suspect a seventy year old well-dressed woman to be involved in such acts, they have no idea who to look for. Along the way, Rose begins to suspect that the conspiracy is much deeper than the thirteen men and decides to pursue it to wherever it leads her. FBI detectives Chuck and Cathy who picked up on the murderous rampage midway through Rose's march across the country are slow to put the pieces together but finally catch up with her near the end. Baker's Dozen is about political hatred and retribution in the extreme and how idealistic beliefs can permanently distort one's perspective regardless of which side is involved.
