Stargate SG-1 : season 5 episodes
- 5.01. Enemies
- The team discover Apophis' ship taken over by the replicators. They
are trapped on another ship, with Apophis and replicators, who speed it
back to their own galaxy. They destroy the ship and escape, but Teal'c
has been brainwashed by Apophis.
- 5.02. Threshold
- Teal'c undergoes an extreme ritual designed to deprogram him, if it
doesn't kill him first.
- 5.03. Ascension
- Carter is found unconscious during a mission. Exhaustion is
diagnosed, but during her consequent leave, she is visited by an alien,
Orlin, who only she can detect. Orlin convinces her the experiments on
the planet she has returned from must cease, but she now needs to
convince Hammond she is not delusional. [Eventually, we discover you can
construct a one-shot stargate from the things you can buy online.]
- 5.04. The Fifth Man
- O'Neill remains behind to help the fifth team member, Tyler, injured
in a Goa'uld attack, while the rest return home for backup. But Hammond
informs them there is no fifth member, and locks down the stargate while
the puzzle is investigated. [Oh, glorious triumph of rationality -- the
team eventually decide, based on the evidence, that there is indeed no
fifth team member!]
- 5.05. Red Sky
- SGC have overridden some security protocols, allowing the wormhole to
pass through a planet's sun, damaging it. All the people will die if the
damage is not reversed, unless they can be persuaded to evacuate. But
they are sure that Freja, their Asgard god, will save them in time, and
stay put. O'Neill contacts the Asgard for help, but they inform him they
cannot, as that would violate their treaty with the Goa'uld, and put all
the galaxy in danger. So Carter must come up with a miracle to save the
sun. She fails, but the effort is good enough to allow the Asgard to
- 5.06. Rite of Passage
- Cassandra [1.15. Singularity]

- 5.08. The Tomb
- SG-1 and a Russian team investigate a planet where a previous Russian
team disappeared. The Russians are acting under additional secret orders
to recover a powerful artifact. But an accident leaves them all
entombed, with a Goa'uld symbiont on the loose.
- 5.09. Between Two Fires
- The Tollan [3.15. Pretense]
have seemingly reversed their policy on giving technology to Earth, and
are offering an ion cannon. O'Neil and the team are suspicious of this
change of heart, and receive a warning of danger, so they ask for 38 ion
cannons, enough for full planetary defence. The Tollan agree. SG-1
discover the cannon are useless against new Goa'uld shields, and the
Tollan High Council is acting under Goa'uld control, building a super
weapon. Then the Goa'uld order the Tollan to use the new weapon on
- 5.10. 2001
- SG-1 discover a race who have friends who offer them help against the
Goa'uld. But Daniel discovers worrying evidence of population decline on
the local planet. These friends turn out to be the same aliens that
nearly destroyed the future Earth [4.16.
2010], before having their coordinates removed from
the SGC computer. Despite warnings from the team, Earth politicians want
to go ahead. The race is on for Sam and the Ambassador (who was her
husband in the other future Earth) to get proof before it's too late.
- 5.11. Desperate Measures
- A dying billionaire snatches a Russian Jaffa prisoner, and Major
Carter, desperate to find a cure. O'Neill enlists disgraced Colonel
Maybourne's help to find Carter. The patient is fading fast, and his
doctors implant the symbiont too soon, desperate to cure him. They plan
to dissect Carter's brain to find out how she survived, but O'Neill
finds her first. Of course, the symbiont takes over, so there is now a
Goa'uld on Earth, eventually captured by Colonel Simmons [John de
- 5.12. Wormhole X-Treme!
- Marty the stranded alien [4.11.
Point of No Return] is now Consultant on the TV
show Wormhole X-treme!, with a plotline that bears a strange
resemblance to a certain Stargate team. He's suffering amnesia, but his
alien friends are back, after the ship approaching Earth. [The 100th
episode, played for meta-laughs.]
- 5.13. Proving Ground
- O'Neill is training some new SG recruits (including Carter's cadet
when there's an emergency, leaving the untried team to save the
- 5.14. 48 Hours
- A Stargate is destroyed as Teal'c is in the wormhole, leaving him
stranded in a temporary buffer. The gate must be shut down, or he will
be erased. Sam works desperately to get him back, while pressure comes
from on-high to restart missions. Maybourne tells O'Neill that Simmons
has the billionaire Goa'uld [5.11. Desperate
Measures], so he goes to him to find a solution. The
Russians reluctantly lend their dialling device to help.
- 5.15. Summit, part I
- The Tok'ra have invented a Goa'uld poison. Daniel Jackson infiltrates
a Goa'uld summit, to poison all the System Lords in one fell swoop. But
an envoy arrives -- it's Daniel's Goa'uld infested ex-girlfriend
[4.13. The Curse].
She represents a new powerful System Lord, Anubis, and Daniel realises
the poison plan would merely create a power vacuum for him to step into.
- 5.16. Last Stand, part II
- The Goa'uld are attacking the Tok'ra base to get the secret poison,
and Carter, O'Neill and Teal'c are trapped in the crystalline
underground. Jackson escapes in a flier from the unpoisoned System Lords
summit to rescue them, crashing the flier on arrival.
- 5.17. Failsafe
- An asteroid is about to obliterate Earth. The Asgard won't help,
because their treaty with the Goa'uld excludes natural disasters
[5.05. Red Sky]. SG-1
repair the crashed flier [5.16. Last
Stand], and attempt to blow up the asteroid. But they
crash, because the rock is made of Naquada -- it is a Goa'uld device. At
the last minute, the team manage to use the hyperdrive to make the rock
pass through the Earth.
- 5.18. The Warrior
- Kytano, First Prime of Imhotep,
has killed him as a false god, and is building up an army of free Jaffa,
leading many successful raids against the Goa'uld. SG-1 go to offer an
alliance with Earth, but O'Neill is worried by the new leader's
readiness to sacrifice his men's lives. Teal'c joins in a mission, only
to discover they have been betrayed. Kytano is really Imhotep, and the
System Lords have been using him to flush out false Jaffa.
- 5.19. Menace
- SG-1 find an android alone on a devastated planet. They take her back
to base, and revive her. Initially she seems friendly and childlike, but
her replicator toys [3.22. Nemesis]
have everyone worried...
- 5.20. The Sentinel
- The illegal NID team [3.18. Shades
of Grey] appear to have broken the Sentinel, a
planetary defence system. A Goa'uld mothership is on its way to take the
planet, and SG-1 need the help of the original team to repair it.
- 5.21. Meridian
- Daniel returns from a mission with a lethal dose of radiation, being
accused by the alien government of sabotage. The rest of the team set
out to clear his name, and save his life. O'Neill shames one of their
scientists, Jonas Quinn, into admitting Daniel actually saved millions
of lives by stopping an explosion. Daniel decides to ascend to a higher
plane as a twisty light being [3.20.
Maternal Instinct], rather than be cured by Jacob
- 5.22. Revelations
- The team is mourning Daniel's loss when Freja comes through the
wormhole: a powerful new Goa'uld ship has killed Thor, and is attacking
a vital Asgard research laboratory, and the Asgard need SG-1's help.
They go, only to discover Thor not dead, but a captive of the Goa'ulds,
being tortured by Anubis [5.15. Summit]
for his knowledge, and that the Asgard are a dying race of clones, with
this laboratory their last hope to save their kind. Lots of to-ing and
fro-ing, but eventually they all escape, with Thor in a coma from a
novel piece of mind downloading technology. The Asgard have found out
from the recently discovered android [5.19.
Menace] how to defeat the replicators, but Anubis
appears to have found new technology even more powerful than the
