Photonic energy life forms mistake the characters in Tom's holonovel for real people. The holodeck characters interpret this as an attack, and soon Dr. Chaotica tries to wipe them out. The only person that can stop him is Captain Janeway in the role of Queen Arachnia of the Spider People.

This was one of the best episodes of Star Trek I've ever seen. I wish there were more episodes like this. Voyager really had the potential to do some interesting stuff, and they did, but there were also many missed opportunities.
