Déjà Vu

The Outer Limits – Season 5

Dr. Mark Crest (Kevin Nealon) has built a teleportation device that uses tactical nuclear weapons to open a wormhole in the space-time continuum. The device is intended to transport some animals eight miles across the desert, but during a test, the wormhole grows out of control and Mark finds himself hurled back in time, to the day before the test took place.
