Steve Simmons was one of the terrorists of Habib Marwan who helped steal the nuclear football after the crash landing of Air Force One. Simmons arrived at the wreckage site of Air Force One with Marwan, Abdul Mahnesh, and another terrorist, and scanned the area for cell phone signals. He located the Jason and Kelly Girard, two campers who found the football, and the four terrorists tracked them down to an industrial structure. Marwan, Simmons, and the other man stalked the Girards, while Abdul tried to kill Agent Jack Bauer outside. When Kelly Girard was lured out, she told Simmons where the briefcase was and gave him the code to open it. He verified that the nuclear football was inside. Jack eventually killed Abdul and the other man, and pursued Marwan and Simmons outside.
