While exploring an unknown region of space, the crew of the Enterprise, except Data is rendered unconscious. When they awake, Data tells them they were out for only a few moments but, several things just don't seem right. Evidence begins to mount that they were out for hours and that Data is, inexplicably, lying about what happened while they were unconscious.
