Shadow of Doubt - Season 1 (2016)

A 31 year old mother of two Michelle Warner vanishes without a trace from her apartment in Houston that she shares with her ex-boyfriend. But this isn't the first time that she's disappeared. With no concrete proof that this time is any different, police and family have only a hunch that chapters from Michelle's checkered past have opened again.

Students at a small-town high school on the outskirts of Dallas suspect an undercover narc is posing as one of them. Theories and threats sound like typical teenage rumoring, until a high school student is found dead in an empty field. A Texas Ranger faces a long list of criminals and misfits who would want to harm a suspected narc.

When 26 year-old Robert Wiles, the promising heir to his family's successful aircraft service company disappears from his Lakeland, Florida office, the FBI have only one clue - a ransom demand from a mysterious "Group X". No witnesses and no forensic evidence surface, forcing investigators to consider that Group X might be a conspiracy within Wiles' company, or Robert Wiles himself.
