Beckett, an American tourist, leaves Athens, Greece with his girlfriend April to escape political unrest there. While driving to their hotel, at a mountain village in the region of Epirus, Beckett falls asleep at the wheel and crashes their car into a nearby house. April is killed in the accident, but while trapped in the wreck Beckett sees a boy being hurried out of the house by a blonde woman.

The next day Xenakis, a local police officer, interviews Beckett and tells him that he was lucky that the house he crashed into was abandoned; however Beckett tells Xenakis about seeing the boy and the woman. After leaving the police station, Beckett goes back to the house with the intention of killing himself, but before he can do so the blonde woman returns and shoots at him. Xenakis arrives soon after and tells him it is safe to come out of hiding, but after he reveals himself Beckett is wounded in the arm as both the woman and Xenakis shoot at him and give chase. Beckett jumps off a cliff and escapes.

After spending the night in an abandoned truck, Beckett is found by a group of hunters who bring Beckett back to town, with one taking Beckett to his house to see to his injuries. Xenakis and the woman soon arrive and Beckett jumps out of a window to escape again. He happens upon two beekeepers who lend him a phone. He calls the U.S. embassy in Athens, but unable to wait for their help Beckett tells them he will make his own way to the embassy. He boards a train to go back to Athens, but Xenakis finds him and attempts to detain him, but Beckett pulls the train’s emergency brake and in the ensuing struggle Xenakis ends up getting shot in the foot and Beckett once again escapes.

Beckett sees posters of the boy being put up by two activists, Lena and Eleni. They tell him that the boy is Dimos Karras, the kidnapped son of a liberal politician who has been allegedly taken by a far-right organization. They drive Beckett to Athens but he is forced to part ways with them to avoid a police roadblock and takes the subway to the U.S. embassy, where he is attacked by a knife-wielding man. Managing to reach the embassy, he is taken in by embassy staffer Tynan, who informs him that April's body had been sent to the embassy, and Beckett is taken to the morgue to view her body.

Beckett tells Tynan about Dimos' kidnappers and the activists, and Tynan offers to take him to an honest cop to sort things out. However after leaving the embassy, Tynan tries to incapacitate Beckett with a taser but he is able to escape. Beckett meets up with Lena and Eleni to warn them about Tynan, but he soon arrives with the police and chases Beckett to a political rally. Shots are fired at the rally and amongst the chaos Beckett takes refuge in a basement where he is cornered by Tynan, who tells him Dimos Karras' father has just been assassinated at the rally. Tynan reveals that Karras had secretly owed an organized crime syndicate money, who then kidnapped his son in retaliation but deflected the blame onto his political enemies, also implying that the U.S. had a role to play in the deception. Fearing that Beckett had uncovered the truth behind Dimos' kidnapping, they went after him. Although Tynan assures Beckett that with Karras dead he is now free to go, Beckett knocks him out.

Beckett returns to the site of the rally to reunite with Lena and Eleni but sees the blonde woman who had kidnapped Dimos.
