After the Starship Reliant beams down Captain Tyrell and Commander Chekov to a planet on an exploration mission, they inadvertently allow the evil Khan, defeated and exiled with his family and henchmen by Captain James T.Kirk and the crew of the USS Enterprise years before, to seize control of the Reliant. Engineering revenge on Kirk, Khan takes the Reliant to the Regula space station where a bunch of scientists have been working on the Genesis Project, a method of regenerating dead planets. The seizure of the Genesis equipment by Khan, forces Admiral Kirk, overseeing a Federation training course on the ship he once commanded, to resume control of the Enterprise and go after his sworn enemy, not knowing that Khan has primed an evil trap.... A change of pace after the almost funereal solemnity of Star Trek: The Motion Picture, director Nicholas Meyer shifts gears for an adventure which is very much in the spirit of the original TV series and is indeed a continuation of the Khan character originally seen in the TV episode Space Seed. Ricardo Montalban makes a fine and ripe adversary for Kirk and co and the whole production has a more comfortable feel, with the actors seeming less out of place than they did in the previous outing. The ILM special effects are excellent and the film ends with a terrifically realised space battle between the Reliant and the Enterprise. Certainly one of the best in the series.
