At his class reunion, Mike finds out Grace, a girl he dated in high school, and her younger sister Chastity, were abducted and raped. Like those who raped Mike's wife, the girls' rapists were never caught. Fixated, Mike is bent on bringing to justice the criminals who raped Grace and her sister. His investigation leads him to members of his high school baseball team and all the way up to a powerful state politician. To expose the rapists Mike will have to put his life on the line. Set in Park Forest, Illinois, the model of a post-World War II suburb, Sisters' Secret shows the dark side of the perfect, planned community.
