John and Eugene look at the final episode of Logan’s Run entitled Stargate. When aliens from another world invade Earth, Logan and Jessica are put on ice, figuratively, and Rem is just spare parts, literally.

Episode Synopsis

Driving through the countryside, Rem and his pets come across a seemingly-injured man who appears to be freezing, despite the weather being temperate enough for Jessica to get away with shat she’s wearing.  They take him back to his city, where his comrades invite the travelers back to enjoy their hospitality.  They’re all dressed in thermal-looking clothes.

Inside, Logan and Jessica are drugged and interrogated.  Rem is discovered to be a highly-sophisticated android and taken away for parts.  Rem, being programmed not to resist humans, goes along more-or-less willingly.

Logan and Jessica are left inside a very hot room without water, and Logan realizes that these people aren’t from Earth.

Rem also comes to the conclusion that they’re not human beings, but apparently, that’s not enough to overcome his pre-programmed directive about resisting human beings, and they take him to be disassembled.  Parts is parts, and Rem’s part work just fine in the alien technology.  Rem surmises that the device is a beacon designed to call the aliens’ homeward.

Logan and Jessica are rescued by Timon, the last human survivor of the city, who lives in the basement.  The aliens arrived a few years back when their spaceship crash-landed nearby.  They are strange, horrible creatures, but they soon began to adopt human form – by stealing the forms of the humans who lived in the city.  Everyone else was killed.

Timon explains that the aliens are probably already creating duplicates of Logan and Jessica.  They go to find and destroy them.

Rem’s parts have been used, but they’re not enough to make the alien doohickey go, so they need more parts to make it go.  They take more of Rem’s parts because parts is parts.  (The technobabble runs strong in this episode.)

Logan and Jessica destroy their forming alien bodies, then track down Rem.  He’s in bits, but in the meantime, he’s been building an anti-alien-doohickey thingamajig.  Their conversation is interrupted because the alien return for more parts from Rem.  Parts is parts, and Rem has parts.

With a gun that Timon was saving to kill himself, Logan takes command of the doohickey room, but, as always, he fails to take the weapons from the fallen aliens and give them to Jessica and Timon.  More aliens come, and they are taken prisoner and left in a swamp to die.

I’ve lost track, but I’m pretty sure they needed more parts, so Rem is further disassembled.  We learn that the doohickey is not just a transmitter, it’s also a matter transporter, and if they get it going, an invasion army will arrive.

In the swamp, which is full of horrible mutants that kill everything, Logan leads Jessica and Timon out of the swamp, which gives them the upper hand because the aliens most certainly think they are dead, but they are not.

In a final assault, Jessica and Timon pump the doohickey room full of liquid oxygen, freezing the aliens to the point of hibernation.  Rem and Logan use Rem’s anti-alien-doohickey thingamajig to destroy the doohickey.

With the aliens incapacitated and stranded from their homeward forever, Timon plans to lock up the creatures that killed everyone in this city, including his son and daughter.  Logan, however, has another suggestion.  “Why don’t you offer them the chance to live in peace with you?”  Yeah.  That’s going to happen.

Rem’s got his parts back, and it’s off they go on their way for more adventures!
