Warning: The following article contains spoilers for The Walking Dead season 8.

The Walking Dead promises a Last Stand for both Rick Grimes and Negan in a brand new trailer and synopsis for the mid-season premiere.

In the trailer below, both Rick's alliance with the destroyed Kingdom and the Hilltop as well as Negan's Saviours are pushed to their limits as they pay the price for waging All-Out War. Watch the trailer below:

Perhaps the most telling moments in the clip centre around Daryl Dixon's (Norman Reedus) vow to become Negan's "worst damn nightmare" and Rick directly warning the leader of the Saviours of his grim fate.

"You set this course, Rick. Who's next?" a calm and cool Negan (Jeffrey Dean Morgan) asks over a walkie-talkie, with Rick (Andrew Lincoln) answering him: "You are!"

In addition to the action-packed trailer, The Walking Dead's US network AMC has also released brand new key art and a detailed plot description for the second half of season eight.

The new synopsis reads: "All-out war has had a devastating impact on every person involved. The communities themselves are fractured. Alexandria has been destroyed, the Hilltop finds themselves pinned, and the Kingdom is shattered — half of them dead, the other half controlled by the Saviors.

"At the very centre — Rick, having been distracted by the conflict, has just returned home to learn that Carl, who heroically shepherded the Alexandrians to safety during Negan's attack, has been bitten by a walker. Once his sole motivation in this otherwise stark existence, Rick is forced to deal with this reality. Carl has always been a beacon of hope, a symbol for the remaining thread of humanity — lessons that the survivors around him would be wise to take with them as this war surges onward.

"But Rick isn't the only person who's living in peril. Aaron and Enid are in a dire situation at Oceanside — unclear if they're in friendly territory, or if they've just made new enemies. Father Gabriel will do his part in attempting to smuggle Dr. Carson safely back to the Hilltop and a pregnant Maggie is wrestling with the many moral gray areas that come with leadership during war. In a standoff with the Saviors, she must decide how to proceed with the dozens of POW lives she's currently in control of, as well as new complications that come with being a leader.

"In addition to the war, Negan continues to deal with struggles within his ranks as workers, traitors, and others' thirst for power cause conflict at the Sanctuary. Having gifted the Saviors a major victory, Eugene's loyalty is repeatedly tested as new obstacles present themselves.

"As all-out war consumes us, the line between good and evil continues to blur. People fighting for what they believe in. Everybody working together for something bigger — to feel safe and have a world worth living in."

These new episodes will have the hefty task of trying to win over long-time fans still fuming over current showrunner Scott M. Gimple's decision to kill off Carl Grimes (Chandler Riggs) in the back-half of the season.

The decision to write out Carl has been widely criticised, even by members of the cast, but Gimple and his team of producers are standing by their decision for now.

"I can't say exactly what happens, but there is a story there and there are remarkable performances by everybody involved, led by Chandler Riggs," Gimple promised.

"And a certain compulsion is given to the story, certain ideas and wishes and even reveals with incredible importance to this season in the overall story."

The Walking Dead is due to return for the second half of its eighth season on Sunday, February 25 in the US on AMC and on Monday, February 26 in the UK on FOX UK.
