It is mid-2268. The Enterprise, under the command of Lieutenant Hikaru Sulu, is returning from a mission to deliver medical supplies to one of Starfleet’s most distant installations. All is routine until the Enterprise comes within a light-year of the planet Mu Arigulon; the ship is suddenly thrown from warp and suffers a momentary power cut. There’s only one injury—a minor one, and the Enterprise is again underway. Before the ship can reach full speed, it hits another distortion, this one much worse. There are a few more physical injuries, but what’s more worrying is an officer that’s entered into a coma…for no apparent reason.
