Kidnapped follows the story of the Cain family, whose son Leopold (Leo) is kidnapped from his prep school. The parents, Conrad and Ellie, hire a private investigator named Knapp to find their son. However, it soon becomes apparent that the Cain family is not as innocent as they seem, and there are many hidden secrets and motives at play.
The show employs a non-linear storytelling technique, jumping back and forth in time to show different perspectives and reveal new information. Along with the main storyline of the kidnapping, there are also subplots involving Knapp's personal life, the kidnappers' motives, and the FBI's involvement in the case.
Kidnapped received critical acclaim for its writing, acting, and complex storytelling. However, it struggled in ratings and was ultimately canceled after one season, leaving the story unresolved. In 2008, Universal HD aired the entire season as a marathon, giving viewers a chance to see the series in its entirety.
