We've known for a couple of months that the first episode of The Walking Dead Season 4 was titled "30 Days Without an Accident," but now we have the titles for an additional three episodes, along with the official descriptions. We also just received a brand new promo video from AMC that includes footage from the new season.

“In the highly anticipated new season, we find Rick Grimes (Andrew Lincoln) and the group fostering a thriving community in the safe haven of the prison. Sadly, in this brutal world, happiness is short-lived and walkers and outside threats are no match for danger brewing inside the fences. The group’s home and new way of life will be thoroughly tested, and their struggle to survive has never been so perilous. Season 4 also introduces several new characters including Bob Stookey (Lawrence Gilliard Jr., The Wire).”

Episode 4.01: "30 Days Without an Accident" - The group lives an ideal life at the prison, and strives to hold onto humanity.

Episode 4.02: "Infected" - The group faces a new enemy; Rick and the others fight to protect their hard-won livelihood.

Episode 4.03: "Isolation" - A group leaves the prison to search for supplies; the remaining members of the group deal with recent losses.

Episode 4.04: "Indifference" - The supply mission faces hurdles; the situation at the prison worsens.

The 16-episode fourth season starts on October 13th in the US. Internationally, the series is expected to return on the same week in most countries, so check your local listings for a specific date and time. Like last season, there will be a break after the first eight episodes, with The Walking Dead Season 4 returning in February 2014 with the final eight episodes. Thanks to SpoilerTV for episode 3 and 4 titles!
