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.

Did You Know?


The production team had hoped to get Kirstie Alley in a cameo role behind her Cheers (1982) costar Kelsey Grammer in the USS Bozeman shots, reprising her role as Lt. Saavik from the movie Star Trek II: The Wrath of Khan (1982), but her asking price was too high for such a small role. See more »


Crusher and Riker play a lengthy poker hand the first time through the loop, before Geordi goes to Sick Bay. In the other loops, the time spent at the poker table is noticeably shorter but Geordi always comes to Sick Bay right after it ends. 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.
