This film tells the real and terrifying story of British hostages trapped by Al Qaeda in an Algerian gas plant in January 2013. As the horrific events unfolded over four days in the full glare of the world's media, Algerian Special Forces stormed the site in an effort to end the crisis, leaving over 37 foreign hostages dead including a number from Britain. This is the story from the perspective of those that lived through it: the hostages that survived and their families. The film combines interviews and research with dramatic reconstruction of key events during the four day siege, which was punctuated by gun battles and daring tales of escape and bravery. The film also raises many unanswered questions, such as how did a convoy of terrorists travel to and gain control of the facility undetected? And who was ultimately responsible for the safety of its workers?
