This new film directed by Michael Bay is adapted from the novel of the same name by Mitchell Zuckoff. It is a political film. On September 11, 2012, an anti-American demonstration took place in front of the U.S. Consulate in Benghazi, Libya. After nightfall, dozens of militants rushed into the consulate. The demonstration turned into a violent conflict, which eventually led to the death of four people, including U.S. Ambassador John Christopher Stevens. This was also the first U.S. ambassador killed by terrorists in 33 years. The film "13 Hours" is based on this real event.
