Muffled screaming, someone crying, and an ax swinging down - these are just some of the sounds that the main characters in 'Voice 4' had to decipher. The show just dropped its newest trailer, and it is, its most blood-chilling yet.

'Voice 4" Drops Another Teaser - Darker than the Rest

With the newest season of the thriller just around the corner, fans are made even more excited every time the show drops an update. This time, a new "Voice 4" teaser is released, and it's truly the best yet, at least for people who love the show and those who love horror films and thrillers.

Check out the trailer below:

This latest teaser for season 4 of "Voice" is so much shorter than the first and the second, but it feels as exciting.

First Two Thrillers Hints Season 4 Twists

It can be recalled that the first one was so much longer and hinted a lot more of what fans can expect when the series is finally released. In the clip, viewers can hear Kang Kwon Joo, the main character played by Lee Ha Na, reliving her past traumas through scary nightmares. Her waking moments are not any better because she's facing a new kind of danger - a posttraumatic stress disorder and a new breed of criminals.

The second teaser, on the other hand, hinted even more. It showed that in this season, Kang Center, headed by Kang Kwon Joo, would be facing some formidable villains - they're not new faces, but the bad guys of the previous season coming back to haunt her.

These are Kim Jae Wook from season one, Kwon Yool in season two, and Park Byung Eun in season three. All three are psycho killers who truly committed their crimes in the most shocking way so viewers cannot forget them.

True fans, however, had to wonder how these characters could even return when they were already dealt with. Kim Jae Wook's character is even reportedly dead already. Fans have to wonder if their return is real or through Kang's hallucinations or nightmares.

The very first season of "Voice" was released back in 2017. It tells of the chilling adventures that an emergency call center gets to have when trying to fight crime using whatever information they can only source from the phone line. The good thing, however, is that the center is led by Miss Kang, who has an uncanny ability to hear things that others cannot.

For three reasons, they fought off small crimes with the help of authorities outside the emergency call center and big crimes involving really psychotic murderers.

Back in March, it was confirmed that both Song Seung Heon and Lee Ha Na would be starring in "Voice 4." There's going to a new murderer in town though, but this time, he has the same ability as Kang Kwon Joo, so that poses a great challenge for the team.
