The film is based on the comic book of the same name by Mike Richardson and Mark Verheiden, and is a sequel to 1994's Timecop starring Jean-Claude Van Damme.

The film stars Jason Scott Lee, with a supporting cast of Thomas Ian Griffith, Mary Page Keller and John Beck.

However, the Society's leader, Brandon Miller, believes he has the responsibility to change history based on a "moral obligation to right the wrongs of the past" and plans to do so by traveling back to Berlin in 1940 and kill Adolf Hitler.

TEC agent Ryan Chang is sent back to stop him, but in the resulting fight, Miller's wife, Sasha, part of the SHA, ends up dead.

Miller sets out to eliminate every TEC operative by traveling back in time and killing their ancestors, making it as if the agents never existed.

Ryan fights his way through rioters at the World Penitentiary, killing an inmate with a grudge against him on his way to confront Miller, but is unable to convince him that what he wants to do is wrong.

This time, the world is even more different due to Miller's interference: Ryan's parents were "killed in the war", Doc has been executed for trying to save her husband and O'Rourke wears an eye patch and has never heard of Hitler.

He is sent to 1881 and prevents Miller from killing an ancestor named Jason in Springfield, Texas, then chases him to 1929 where he saves a Frances in a Chinese restaurant.
