'13 Hours: The Secret Soldiers of Benghazi'

CHICAGO -- "13 Hours: The Secret Soldiers of Benghazi" is a new movie about the storming of a U.S. compound in Libya that killed six Americans, including the ambassador.

The film shows what happened when six elite, ex-military men took on terrorists who attacked the U.S. diplomatic compound in 2012.

"It's just something we had to do because the truth wasn't being told. Politicians weren't honoring the guys that sacrificed their lives. They were just trying to spin the story to benefit themselves and we got kind of ticked off," former Marine John Tiegen said.

Their story is already a best-selling book.

"The majority of us sustained some kind of injury that night. Thirteen hours is a long night to fight," Tiegen said.

"I had 20, 30 holes in me, nothing much," former Mark Geist said.

"13 Hours" is directed by Michael Bay, who is behind the "Transformers" movies.

"That night there were a lot of explosions. I was involved in three of them, so I think it's kind of the perfect person for the movie. He's always been a very patriotic person. In almost every one of his movies I've ever see, he covers that teamwork and dedication and the honor of the team," Geist said.

"The movie's just gonna give us a wider base of people who actually understand what happened that night, the sacrifice that the average American makes besides a soldier," Tiegen said.

"The most important thing is telling the story and honoring the four Americans that died that night," Geist said.
