In 2007, during the Iraq War, a Georgian contingent of the coalition forces saves the life of American reporter Thomas Anders, although one of his colleagues, Miriam Eisner, is killed in the process. One year later, in 2008, he returns to Los Angeles, California but soon goes to Georgia on the advice of some of his friends in Tbilisi, who suspect that a large conflict is brewing. He, along with his cameraman Sebastian Ganz, delve deeper into Georgian life as conflict escalates and they get caught in the crossfire when an air raid strikes a local wedding they stumble upon.

With members of the wedding party, including Tatia Medoev, and the help of Georgian soldier Rezo Avaliani, who had earlier saved them in Iraq, Thomas and Sebastian's mission becomes getting their footage of an atrocity by Russian irregulars out of the country. They find themselves faced with international apathy due to the opening of the 2008 Olympic Games and their flight leads them to the Gori. The film ends with a long series of testimonials from Georgian citizens who lost family members during the conflict.
