Star Trek: The Next Generation - Clues

VHS, PARAMOUNT

En route to investigate a mysterious planet, the Enterprise TM passes through a "worm hole" in space which knocks everyone but Commander Data (Brent Spiner) unconscious. When the crew is revived, the ship has been transported a full day's distance away, yet only 30 seconds have passed. Dr. Beverly Crusher (Gates McFadden) is surprised to find that an experiment of hers has progressed a full day, so she brings it to the attention of Captain Picard (Patrick Stewart). Other clues point to the fact that, in actuality, the crew lived the missing day, and have lost their memory of it. Ordered to investigate, Lt. Commander Geordi LaForge (LeVar Burton) discovers that the ship's chronometer, and other devices, have been tampered with-by Data. When Picard confronts Data, he refuses to reveal what he knows. In order to find out what really happened, Picard offers the Enterprise to retrace its steps back to the mysterious planet-and into a dangerous encounter.
