Synopsis
After returning from another trip through the Guardian of Forever, Kirk and Spock find that no one on the Enterprise remembers Mr. Spock or who he is. In fact, another man, an Andorian, claims to be the first officer of the Enterprise. History records that a seven-year-old Spock died during a maturity test, and thus never served in Starfleet. Realizing they changed history in some way, Spock uses the Guardian again to go back to Vulcan and save his own life. Will he succeed or will he only further alter the timeline?
