The new trailer for "Transformers: The Last Knight" features blood dripping from a crucifix, Nazis on the rise and Optimus Prime seemingly dead.

"Transformers: The Last Knight" is a 2017 science fiction-action film that is the fifth installment of the live-action "Transformers" film series and a sequel to "Transformers: Age of Extinction."

On December 7, Paramount released the first teaser trailer for the upcoming film, narrated by Anthony Hopkins. The trailer sets the stage for the war between the Transformers and humans. The trailer also hints that Optimus Prime might be on the wrong side.

The first half of the clip is mainly concerned with the history of human violence, with soldiers creeping through the woods while flaming arrows come from different directions. Generally, it sends an important message about the realities of human condition.

However, the most intriguing part of the trailer is that which shows the frozen carcass of Optimus Prime spinning through space, seemingly dead.

Based on the synopsis for the upcoming film, "The Last Knight" is set to explore the long connection of Cybertronians--the race, the Autobots and Decepticons-- on Earth. According to reports, the sword of Optimus Prime will be linked with the Excalibur.

The film will feature "Once Upon A Time" star Liam Garrigan as King Arthur in "The Last Knight." Mitch Pileggi is also joining the cast, but her role remains undisclosed as of this writing.

Directed by Michael Bay, "Transformers: The Last Knight" is set to hit theaters on June 23, 2017.
