The investigation reveals that Pam Smart slept with her husband's triggerman, 15-year-old Billy Flynn; salacious details emerge in the first broadcast gavel-to-gavel murder trial in America.

24-year-old Gregg Smart is found brutally murdered inside the entrance to his condo; investigators arrest three local teens who have a connection to the victim's wife, Pam, and begin suspecting her of orchestrating her husband's murder.

As the trial continues, the prosecution plays secret audio recordings of Pam Smart that shock the courtroom; Pam takes the stand in a desperate bid to prove that Billy acted on his own motivations -- and killed Gregg in a lust-filled rage.
