The Pendulum

Plot:

Gunnar Malstrom is one of the leaders of the Pendulum, a secret terrorist organization seeking to overthrow the United States government. The IMF is informed that the Pendulum is shortly planning a major attack on the government, code-named Nightfall. With no knowledge of other members of the Pendulum, the IMF lures Malstrom to the headquarters of a phony corporate conglomerate, where they learn bits and pieces of the plan -- but fail to uncover that the official who is supposedly the target of Nightfall has already been replaced by a Pendulum double.
