After the shocking events inside Alexandria during the midseason premiere of "The Walking Dead" season 6, more breath-taking scenes are coming in episode 10.

Based on the trailer for the upcoming episode titled "The Next World," Rick Grimes (Andrew Lincoln) and Daryl Dixon (Norman Reedus) will once again look for supplies for the group. But it seems like the walkers will not be the only ones who will give them a hard time before they can manage to secure some items for survival.

According to the synopsis for the episode, "A simple scavenging run proves to be more tricky, when the survivors are not the only ones after a goldmine of supplies."

This means that Rick and his group will be encountering another group of humans, who could be deadlier and more dangerous compared to the walkers.

"We're now coming upon a group of people who are formidable [Negan and the Saviors] and somebody that Rick is not going to be able to take care of as easily as he did with the people at Grady Memorial, Terminus or the Governor's group," executive producer Greg Nicotero told The Hollywood Reporter. "This is a whole other animal and we're taking the show in a whole other direction. The finale is the 15th episode I've directed and every episode is a different set of challenges. I love [the midseason premiere] but the finale is the best work I've done on the show."

Meanwhile, the trailer also reveals that Michonne (Danai Gurira) might be in grave danger after offering help to a man that she just met. The man just shrugs off her offer. But the next scene shows someone pulling out a knife before revealing Michonne's shocked and scared face. Is the knife intended for her?

"The Walking Dead" season 6 episode 10 airs Sunday, Feb. 21, on AMC.
