There are not a lot of Canadian movies around and terrorism is definately a rare topic. And this is a story about it, and it is a pretty good one.
No one is born a terrorist. Mohamod is no exception. He refused to join the group at the first place, till he had issues. The university rejected his application, no one talked him at the bar, the main stream community did not accept him either. He did a stupid thing, stealing at the bar and was caught. After bailed out by a terrorist, Mohamod joined the group and quickly became a key player.
The Canadians are very thoughtful, in most cases. The director did not accuse Mohamod with no reason. Instead, he tried to dig deeper and he discovered some of the reasons, at least from the point of how a civilian was converted to a terrorist.
