By 2270, the Enterprise is equipped with a holodeck in its Recreation Room. A control console in the center of the large chamber allows for such holographic simulations as a sunny beach, or a pleasant woods. When the Enterprise is infected by highly charged subatomic particles in 2270 (stardate 3183.3), the ship's computer turns on Helmsman Sulu, Dr. McCoy and Lieutenant Uhura in the holodeck, trapping them first in a pit in the woods, then in an icy blizzard, and finally in a hedge maze.
