In 1566, Elizabeth Tudor faces tremendous opposition from Parliament for ruling England without the help of a husband. Instead, she turns to her Privy Plot Council for help, only to discover from her royal herbalist that a woman has drowned in a tub of starch. Soon another garment worker soon meets the same rigid fate. Elizabeth becomes unbending in her attempts to solve the murders, as well as iron out the problems of her kingdom. But with her list of suspects growing—and firm evidence pointing to those she trusts the most—Elizabeth must hang the murderer out to dry or risk losing her reign… or her life.
