series, and is often credited with renewing substantial interest in the franchise. Plot In 2285, Admiral James T. Kirk oversees a simulator session of Captain Spock's trainees. In the simulation, Lieutenant Saavik commands the starship on a rescue mission to save the crew of the damaged ship Kobayashi Maru, but is attacked by Klingon cruisers and critically damaged. The simulation is a no-win scenario designed to test the character of Starfleet officers. Later, Dr. McCoy visits Kirk on his birthday; seeing Kirk in low spirits due to his age, the doctor advises Kirk to get a new command instead of growing old behind a desk. Meanwhile, the starship Reliant is on a mission to search for a lifeless planet to test the Genesis Device, a technology designed to reorganize dead matter into habitable worlds. Reliant'''s Captain Clark Terrell and first officer Commander Pavel Chekov beam down to evaluate a planet they believe to be Ceti Alpha VI; once there, they are captured by the genetically engineered tyrant Khan Noonien Singh explaining that they are on Ceti Alpha V. Fifteen years prior, Kirk exiled Khan and his fellow supermen to Ceti Alpha V after they attempted to take over his ship. The neighboring planet exploded, devastating the surface of Ceti Alpha V. Khan implants Chekov and Terrell with indigenous eel larvae (which killed several of his followers, including his wife) that render them susceptible to mind control, and uses them to capture Reliant. Learning of the Genesis Device, Khan attacks space station Regula I where the device is being developed by Kirk's former lover, Dr. Carol Marcus, and their son, David. Kirk assumes command of Enterprise after the ship, deployed on a training cruise, receives a distress call from Regula I. En route, Enterprise is ambushed and crippled by Reliant. Khan offers to spare Kirk's crew if they relinquish all material related to Genesis; Kirk instead stalls for time and, taking advantage of Khan's unfamiliarity with starship controls, remotely lowers Reliants shields, enabling a counter-attack. Khan is forced to retreat and effect repairs, while Enterprise limps to Regula I. Kirk, McCoy, and Saavik beam to the station and find Terrell and Chekov alive, along with the slaughtered members of Marcus' team. They soon find Carol and David hiding Genesis deep inside the nearby planetoid. Khan, having used Terrell and Chekov as spies, orders them to kill Kirk; Terrell resists the eel's
