Quoted from cover:
"In the year 2004, time travel is not only a reality, it's an opportunity - for criminals of the future to alter the past for profit and power. International superstar Jean-Claude Van Damme stars in this sci-fi action-thriller as embittered timecop Max Walker - toughest member of the elite "Time Enforcement Commision" which was created to enforce one simple rule: No One Goes Back.
But Walker may have met his match in the person of Senator McComb (Ron Silver), a corrupt, ruthless politician who's determined to reinvent history, get rich and buy his way into the White House. Walker's relentless pursuit leads him to the year 1994, where he is confronted by an even more powerful force: his own interrupted past with beautiful wife Melissa (Mia Sara).
Can Walker resist the impulse to change his own future and still battle an evil that threatens to rip apart the very fabric of time itself?"
