By Any Other Name
Summary
Beings from the Andromeda Galaxy steal the Enterprise, technologically modify it, and attempt to return home. Kirk, Spock, Bones, and some crew members beam down to a planet's surface and find a group of people who demand Kirk surrender the ship by paralyzing everyone except Kirk. These people are the inhabitants of the planet Kelvan in the Andromeda galaxy. They crossed the intergalactic boundaries and intergalactic space to the Milky Way to find a sustainable system for their people on a journey spanning over 300 years. Soon, Rojan controls the Enterprise and, along with his people, immobilizes the entire crew aboard and begins the journey for Andromeda. Upon reaching the intergalactic boundary, Spock and Scotty make a plan to blow up the Enterprise to defeat the Kelvans' mission, but Spock says no.
