Sophia Maguire (Laura Innes) from "The Event" is the leader of the detainees being held at the Mount Inostranka Detention Facility. Sophia and her people are quarantined after being discovered at an unexplained crash site in the Brooks Mountain Range in Alaska. Right before she and the injured passengers are discovered, Sophia leaves her sons Thomas (Clifton Collins, Jr.) and Simon Lee (Ian Anthony Dale) in charge of taking care of those who are able to evade capture. The nature and the origin of the captives is unknown, but it is very clear that Sophia and her people are not of human origin. After President Martinez (Blair Underwood) finds out about the detention facility, he and Sophia work together to free the captives and tell the American public about their existence.
"You wanted the truth, I'm giving it to you."
"That would be a mistake, Mr. President. My people have been waiting for 66 years. Their patience is running out."
