Kenny and Betty Anne Waters were children of an indifferent mother. Forced to fend for themselves, they were very close before they were eventually sent to separate foster homes. Now a wife and mother of two sons, Betty Anne's life is still centered on her brother, who had a troubled youth and is currently serving a life sentence in prison. Kenny was initially taken in for questioning by Sergeant Nancy Taylor over the murder of his next-door neighbor, Katherina Reitz Brow on May 21, 1980, in
Ayer, Massachusetts. He was released, but two years later, based on new testimony presented by Taylor from his ex-wife Brenda, and ex-girlfriend Roseanna, he was arrested and tried. The evidence presented at Kenny's trial is circumstantial, but coupled with limited blood-typed evidence, he is convicted of first degree murder and sentenced to
life imprisonment without parole. When Betty Ann discovers that Kenny tried to commit suicide three years into his sentence, she decides to go back to school and become a lawyer so she can exonerate him. Her husband is skeptical and unsupportive, and eventually they split up and divorce. When her schedule takes time away from her sons, they decide to live with their father. Struggling in school, demoralized and exhausted, Betty Anne stops going to classes, until Abra, a classmate, motivates her to continue. Betty Anne realizes that the new field of
DNA testing could be the key to overturning Kenny's conviction, as only blood types had been matched at the time of the trial. She contacts attorney
Barry Scheck from the
Innocence Project. The backlog of cases will mean waiting at least 18 months, unless she can pass the bar exam and find the blood evidence to have it tested. She passes the bar exam, but is then told the evidence was destroyed six years earlier. Refusing to give up, Betty Anne learns that Nancy Taylor was fired from the police department for attempting to frame another officer, and when she and Abra travel to the Boston courthouse and plead with the supervisor to look through the evidence, it is found. The DNA results come back and establish that the blood was not Kenny's. Betty Anne and Kenny are overjoyed anticipating his release, but District Attorney
Martha Coakley refuses to vacate the conviction, claiming that there was still enough evidence to convict Kenny as an accomplice. Kenny is convinced that the authorities will find a way to keep him in prison to avoid admitting their mistake, but Scheck advises Betty Ann that their discovery not only proves Kenny's innocence, but also that the main witnesses against him were lying. Betty Anne, Abra, and Scheck visit the two main trial witnesses, Kenny's ex-wife and his ex-girlfriend. Both tearfully confess that Sergeant Taylor coerced them into
perjuring themselves at Kenny's trial. Kenny's conviction is vacated and he is freed from prison in June 2001. Betty Anne is able to persuade his teenage daughter that he never stopped trying to reach out to her while he was in prison, so Kenny is finally able to be reunited with his daughter, as well as with his sister and her sons. The epilogue states that Betty Anne continues to work with the Innocence Project to prevent wrongful convictions. She also won a major settlement against Nancy Taylor and the Ayer police department, although Taylor was immune from criminal prosecution due to the statute of limitations. The real killer of Katherina Brow was found Joseph Leo Boudreau. ==Cast==
