New York District Attorney Roger "Butch" Karp faces one of his most challenging and dramatic cases when his wife Marlene Ciampi learns that his office has indicted the wrong man for murder. Approached by the mother of the accused, Marlene risks her life to prove his confession was false. Now Karp, who has dedicated his efforts as DA to the "institutionalization of virtue," must not only admit that his system of checks and balances failed, he must go up against his own NYPD to catch and then successfully prosecute the real killer.
