Zero: An Investigation into 9/11 posits that the official narrative of the events surrounding the attacks of September 11 cannot be true. The film explores the various facets of that premise by testing scientific evidence and dramatic witness testimony against the official account to demonstrate its many shortcomings, contradictions, gaps and omissions. The question is posed that if the thesis of this film is correct, and the official narrative is false, then the entire justification for the ensuing wars of terror, rampant human rights abuses, and the curtailment of civil liberties, is built on a complex series of outrageous lies.
