Civic Duty (2007)

Terry Allen appears to be a model American citizen. He dresses well, has a charming wife, and makes a decent living as an accountant. But after he loses his job and his mortgage application falls through, he quickly sinks into a media-fueled obsession with his country's war on terrorism. When a Muslim student named Gabe Hassan unexpectedly moves in next door, Allen’s fears are further exacerbated. He shadows Hassan, examines his trash, and decides to file a report with the local FBI office. Meanwhile, Allen’s wife watches in horror as her once liberal husband scours most-wanted lists and monitors Hassan’s home with the trademark mania of a government agent gone-wrong. While FBI agent Hillary drags his heels, Allen takes matters into his own hands and unlawfully breaks into Hassan's home. As Allen becomes more entangled in his neighbors business, the line between terrorist and nationalist becomes frighteningly unclear.
