Episode cast overview:


Unbeknownst to the crew, the Enterprise is caught in a time loop where they are continually reliving the same day. The Enterprise approaches a temporal distortion from which another Federation vessel is emerging. The evasive action action they take - using the tractor beam to push the oncoming vessel away from them - is unsuccessful and the Enterprise is destroyed, at which point the time loop brings them back to the beginning and they relive the sequence all over again. Several members of the crew however begin to have a serious case of deja vu and become convinced that they are reliving the same day, over and over. Data has an idea that might get them out of it.

Captain Bateson believes he's still in the year 2278 and just left spacedock a few weeks earlier. 2278 is toward the end of the service life of the original starship Enterprise, NCC-1701. Since every starship Enterprise has been the flagship of the Federation fleet, it stands to reason that every contemporary Federation starship captain would be familiar with that ship and its commanding officer. But when Captain Picard introduced himself as the commanding officer of the starship Enterprise, Captain Bateson casually replied that "your vessel is not familiar to us." He should have suspected right then that that was neither the Enterprise he knew, nor its captain. See more »

I remember when this episode first aired... It was spooky, surreal, and suspenseful. Usually in Star Trek episodes you can spot the "solution" beforehand, or else a character reveals a plan that you know will work, although you assume that it will be a close call. Not so here. Because of the time warp, you know that somehow things will turn out okay, but you really don't know how, and the anxiety level ratchets up each time the crew fails to avert disaster. The show honestly leaves you hanging until the end. This was "Groundhog Day" in the year BEFORE Groundhog Day. (Connection????) The acting is amazing because even though the same scene is repeated several times, the viewer remains rapt in attention. Underrated, sublime episode.
