It's about a guy from the army who's convicted of manslaughter and he's in jail for ten years and he's sending letters to his daughter Casey. So the guy gets paroled after eight years and he boards this plane called the Jailbird which is basically a flying prison that's sending a bunch of other inmates to a higher security prison. But like when they're in the air, one of the prisoners starts a huge riot and hjiack the plane and stuff but some of the other people on the plane have to figure out how to stop the prisoners before they land and split up. That is pretty much all I can say without giving away the movie, but it's an action film with Nic Cage.
