AMC's award-winning The Walking Dead Webisodes series returns to and AMC's YouTube Channel on October 1 with three new installments. The newest series - "The Oath" - was executive produced, directed and conceived by Greg Nicotero, executive producer, director and special effects makeup designer on the hit show.

In the three webisodes (7 to 10 minutes each), the lone survivors of a massive walker-attack, Paul (Wyatt Russell, Cowboys & Aliens) and Karina (Ashley Bell, The Last Exorcism), speed across the countryside, frantically searching for an aid-station, as one of them slowly bleeds out from a wound. Finally coming upon a hospital that has not been overrun, at first feels like a blessing, but could soon turn to misfortune, as a seemingly benevolent doctor (Ellen Greene, Little Shop of Horrors) may hide a darker agenda.
