The crew of the USS Enterprise arrive at the planet M-113 to deliver supplies, where Dr. McCoy has a reunion with his one-time love Nancy, and the crew are plunged into a murder mystery when one of the landing party mysteriously ends up dead. If this sounds familiar, that's because the plot is largely taken from the TOS's first broadcast episode, "The Man Trap" (albeit with a subplot involving androids that's more loosely taken from another early TOS episode, "What Are Little Girls Made of?"). Where this film differs is that the titular Ömer the Tourist gets teleported into the story's events as a way of escaping a Shotgun Wedding, leading to hilarity ensuing as he screws around with the progression of the story.
Contrast with The Man Who Saves the World, which likewise takes stock effects shots from an American sci-fi franchise (Star Wars), though does it with a new storyline.
Tropes include:
- Captain Ersatz: While most of the English character names are generic enough that this film is able to get away with keeping them, the creators were apparently concerned enough about Spock to change his name to "Mr. Spak", though he keeps the pointy ears.
- Composite Character: The film's version of Professor Crater also incorporates some aspects of Roger Korby from "What Are Little Girls Made of?" — he's not an android himself, but he does have some vaguely-defined Evil Plan involving the androids he's found.
- Fish out of Temporal Water: Ömer, a man from the late 20th century, gets transported to the 23rd century, leading to all sorts of wacky hijinks.
- Here We Go Again!: At the end of the story, Ömer is returned to his own time... right back to the shotgun wedding he was saved from. This time, however, he manages to escape courtesy of a Vulcan nerve pinch.
- Mr. Fanservice: The android who accompanies Nancy for most of the story is a muscular, oiled man wearing a loincloth.
- Noodle Incident: It's never explained very clearly why Ömer is being forced to take part in a shotgun wedding, beyond some vague reference to the woman he's forced to marry being part of a Turkish Mafia family.
- Shotgun Wedding: Ömer's being forced to be the groom in one of these leads him to pray to the gods to get out of the situation, leading to him being transported to the 23rd century.
- Spoiler Cover: The film's official poster spoils the ending twist of Ömer being turned into a Vulcan.
- Stock Footage: All the shots of the Enterprise are taken from what appears to be a film recording of a TV screen.
- Red Shirt: Plot-wise, the same minor crewmembers who get killed off in "The Man Trap" mostly die here as well. However, this film's costume department apparently didn't have access to any red fabrics, as the security officers wear green shirts.
- Teleporter Accident: For some bizarre reason, the process used to teleport Ömer back to the 20th century turns him into a Vulcan, allowing him to nerve pinch some Mafia thugs.
- Troll: As soon as Ömer gets on-board the Enterprise, he starts messing around with the ship's controls, much to his great amusement (and as much irritation as Spak's nature will let him show).
- Whole-Plot Reference: The main storyline is taken beat-for-beat from "The Man Trap", albeit with the android subplot loosely taken from "What Are Little Girls Made Of?", and the film does use the salt vampire's shape-shifting ability to throw in references to a few other episodes such as "Arena" and "Amok Time". Perhaps most bizarrely, it also manages to be this to an unproduced TOS script called "Hitler's Father", which had the Enterprise crew unwittingly transport a 19th century Austrian gentleman by the name of Alois Schicklgruber (who would later change his name to Alois Hitler, and even later still, sire Adolf) on-board.
