A.P.E.X is a 1994 science fiction action film directed by Phillip J. Roth and starring Richard Keats, Mitchell Cox, Lisa Ann Russell, and Marcus Aurelius.

An accident introduces a deadly virus to 1973, which activates the project's automatic countermeasures.

Attack robots are sent to the past in an effort to eliminate the virus carriers.

They fail, and Sinclair returns to 2073 to find the Earth in ruins, ravaged by both the virus and a constant stream of attack robots.

Sinclair returns to the project lab that is now in ruins and uses the time travel equipment there to prevent the original cause of the accident.
