When war broke out in Iraq in 2003, Roy Miller (played by Matt Damon) was sent to Look for WMD, because Saddam's government has been hit hard, and the WMD that the United States wants to use weapons of mass destruction has become an excuse to send troops

Based on the intelligence received, Roy led the team to Iraq, and went to traps and dangerous checkpoints to find weapons , but many times it failed. Miller gradually became suspicious of the source of the intelligence. Once in Xiongdong, he ran into a local man, Fa Hadi. The one-legged man told Miller that key figures in Iraq were gathering, and El on the wanted list was among them. Roy went to investigate and found that Al was inextricably linked with the US government, and a huge conspiracy might be hidden behind it.

Roy wanted to investigate but was blocked, so he could only find out the truth by himself regardless of opposition, but unexpectedly received a letter from the military obstruction. Roy knew that he had to race against time in order to find key evidence, reveal the government's conspiracy and the truth of the matter, and suppress the imminent war in Iraq.
