After the murder of a nun in the Church, Goren and Eames investigate and realise that someone has tried to cover up part of the crime. Their investigation leads them to a young man named Eddie Roberts, who in turn inadvertently leads them to his older half-brother, Jimmy Jones, who was assaulted in a baseball field seventeen years earlier and left with debilitating injuries. Goren and Eames soon realise that the key to the nun's murder is the young woman who watched Jimmy's attack, and the only way they can get Eddie to take responsibility for his crime is to find this missing witness.
