The movie is based on the relationship of 9/11 terrorist Ziad Jarrah and his wife Aysel Sengun. However, changes were made as the film is not meant to be a docudrama; Jarrah is renamed as Saeed while Sengun was renamed as Asli, and Jarrah trained for Al-Qaeda in Afghanistan while Saeed is assumed to have trained in Yemen. The World Trade Center towers were also not shown, although footages and photos of its collapse were used. Everything else, including the time frame and settings, is an exact dramatization of reports regarding Jarrah's life in the 9/11 Commission Report.
