When a prominent atheist leader is kidnapped, ransomed and murdered, Detectives Goren and Eames interview the victim's granddaughter who was also kidnapped but survived and the suspects include more family members, including the dead woman's son - now a reverend with a prison ministry. However, when two of the kidnappers turn up dead, the investigators look for a double-crossing mastermind who pulled the strings but left no trail to follow.
