The Enterprise comes upon another Star Fleet vessel drifting in space. They find that the crew has killed each other off and there is only one survivor, a Betazoid crew member. Deanna tries to communicate with the Betazoid crew member to find out what happened. The Enterprise crew then starts to exhibit the same problems that the other ship experienced. Humans appear to be not be able to have deep sleep (REM)anymore. Only Data, the android, and Deanna, the Betazoid, are immune to the loss of deep sleep. Deanna and Data become the only crew members who can work to find out how to get out of the situation. The scariest moment of the episode is when Doctor Crusher is working in a room with the dead victims from the other ship. With her lack of REM sleep, she hallucinates that all of the corpses all of sudden sit upright on the tables that they are laying on.
