A convict in Mississippi is reprimanded by a dictatorial warden, who puts the convict in a solitary confinement box located outside during a huge storm in which several tornadoes touch down. When the storm subsides, the box has been destroyed, but its former occupant has escaped and wreaks havoc on those that wronged him. Mulder and Scully try to figure out his next move and how the convict is able to move through seemingly impassable barriers.
