ommander Riker has not been sleeping well but Dr. Crusher can't find anything wrong with him. He is constantly exhausted and has images of object in his mind that he can't quite place. He is not the only one with a sense of deja vu and with others, manages to piece together what has been happening. It would seem they are being taken from the ship during their sleeping hours by a race conducting experiments on them. Who they are and what they hope to achieve is unknown but everyone agrees it must be related to the inter-dimensional hole in space that is somehow being created in one of the cargo bays.
