Investigators Lise Olsen and Fred Paige are on a mission to examine the confessions of inmate Edward Harold Bell. He has confessed to the brutal murder of eleven teenage girls. But is he a serial killer or just an attention-seeking liar?

Prisoner Edward Harold Bell has retracted his confession. And when investigators Lise Olsen and Fred Paige look into the only man ever convicted for any of the eleven murders, they uncover shocking inconsistencies, unlawful police tactics, and a deadly miscarriage of justice.

With Edward Harold Bell as their number one suspect, investigators Lise Olsen and Fred Paige are determined to find justice for the eleven murdered girls of Galveston County. The search for buried clues proves frustrating, but they find evidence that puts Bell at the epicenter of a gruesome map.

Investigators Lise Olsen and Fred Paige have uncovered a geographic link between Edward Harold Bell and three pairs of murdered girls. They're now zeroing in on the remaining victims to see if they can connect the dots, hoping forensics will provide the final piece of the puzzle. There's a tenuous but compelling link tying Bell to 16-year-old Kimberly Pitchford. And the discovery of physical evidence from the murder of 14-year-old Brenda Jones provides a possible DNA link plus a chilling MO that ties the two cases together. With Bell's next parole hearing on the horizon, a forensic psychologist delivers a damning assessment. After a complicated search, Lise and Fred interview a woman who describes being kidnapped at gunpoint and raped by Ed Bell.

Determined to establish a definitive link between Edward Harold Bell and the Eleven, investigators Lise Olsen and Fred Paige examine the last victim-12-year-old Suzie Bowers. Bell's former neighbor pinpoints the precise location of his infamous red caboose trailer, only two miles from where Suzie's body was found. Later, the investigation moves to Panama where Ed Bell fled after gunning down a Marine in suburban Galveston in 1978. Bell spent 14 years on the run, and Lise and Fred are looking for anything that could link him to the Galveston murders. They learn why Panama was the perfect refuge for a predator and finally track down Bell's former girlfriend who makes an impassioned plea. Will a message from the woman who loved him make Bell talk?

With Edward Harold Bell's parole date quickly approaching, investigators Lise Olsen and Fred Paige face mounting pressure to find definitive proof that links him to the Eleven.
