Synopsis by Hal Erickson
While opening a wormhole in the space-time continuum, scientist Mark Crest (Kevin Nealon) is suddenly trapped in a time loop. He keeps returning to the day before his exploration of the wormhole, and in each case the same thing happens and he is thrust back in time. Gradually, Crest comes to the conclusion that there's a saboteur in the works -- but even knowing this, will he ever be able to get the continuum back on track again? "Déjà vu" originally aired on July 9, 1999.
