The Walking Dead: Dead City trailer: Lauren Cohan and Jeffrey Dean Morgan ... trends now

The official trailer for the upcoming horror-drama series The Walking Dead: Dead City was released on The Walking Dead franchise's official YouTube channel on Thursday.

The clip followed Maggie Greene and Negan, played by Lauren Cohan and Jeffrey Dean Morgan, who made their way to Manhattan in order to rescue the former's kidnapped son, Hershel.

The series, which had its premiere date revealed to the public this past March, will serve as one of the follow-ups to The Walking Dead.

The trailer began with Maggie and Negan boarding a boat, and when the latter asks her 'where the hell we're going,' she simply replies: 'Manhattan.'

After several shots of the devastated metropolis are shown, Greene tells her former adversary that 'a few weeks ago, we got raided,' and he discerns that 'they took your kid.'

Perlie Armstrong, played by Gaius Charles, then enters a bar with a wanted poster bearing Negan's visage before the show's lead characters come across a zombie-surrounded Madison Square Garden.

After the man who murdered Greene's husband asks her why she wants his help, she replies that he knows the man who kidnapped Hershel, better known as The Croat, played by Zeljko Ivanek.

The Croat later finds out that his former adversary has come to Manhattan, after which Maggie and Negan encounter a group of survivors with whom they later share dinner.

It is then revealed that Ivanek's character is conducting biological experiments on zombies, and the survivors agree to help the former adversaries find the criminal.

After The Croat intimidates Hershel, played by Logan Kim, by tying him to a chair and brandishing a hatchet, Maggie states that her plan is to 'get him to tell me where my son is, then we kill him.'

Greene and Negan then enter a former sports arena and take out numerous zombies before Armstrong tells her: 'I don't know why you're with that man I'm looking for, but I will get to you.'

A rapid-fire montage then ensues, during which Maggie erratically drives an ambulance before passing out after crawling through a tunnel.

The trailer concludes after The Croat ominously tells an unseen captive that they will 'like it here' before Greene is confronted by a grotesquely mutated and multi-limbed zombie.
