The new trailer for "Attack on Titan" live-action film was released with English subtitles.

At the start of the trailer posted to YouTube, the narrator details the lives of the people living behind the great wall that was built to protect residents from the giant human-eating Titans.

"Over 100 years ago, most of humanity was consumed by the Titans that suddenly appeared," the narrator said. "The small percentage of humanity that survived constructed a giant wall, and lived peacefully."

The film will show how the citizens react when the Titans come to take over their peaceful society again after a century. One of the characters said that people saw Titans over the wall, but others continued to believe that they were just a myth.

Suddenly, a huge Titan crashes into the wall making a crowd of people disperse.

"One day humanity remembered the fear of being dominated by them [Titans]," the narrator continued. "The humiliation of living in the cages we call walls."

Some of the soldiers started to doubt themselves, saying that the Titans "are immortal" so there is no way that they can win a fight against the large beasts.

But they gain the courage to keep fighting. They are on a mission to claim back their peaceful lives.
