Enemy Alien (2011)

A Japanese American filmmaker finds echoes of his own family's World War II internment in post-9/11 arrests of Muslim immigrants and joins the struggle to free Farouk Abdel-Muhti, a Palestinian activist. Farouk organizes resistance among his fellow detainees, incurring abusive retaliation from his captors, as Homeland Security officials investigate the documentary itself, arresting Farouk's son.
