|SG-1 Season 1|
The Stargate Program is shut down after Senator Robert Kinsey's visit, but SG-1 still plans to stop the Goa'uld invasion. They gate to what they think is the Goa'uld home world, but soon discover they are on a Ha'tak vessel, lead by Apophis and Skaara, now host to Klorel. The ships are also now heading straight for Earth.
Senator Robert Kinsey has shut down the Stargate program. Major General George S. Hammond went to him twice, and the second time he was thrown out of Kinsey's office. He then went to the Secretary of Defense, the Joint Chiefs of Staff, even the President of the United States himself; but it would be political suicide for any of them to override the Senate Appropriations Committee.
Knowing that the slaughter that took place in There But for the Grace of God could happen in this reality, Dr. Daniel Jackson convinces his team members to violate orders. They then arm themselves, dial the address Jackson got in the alternate reality, and, after sending a MALP to confirm the conditions on the other side are safe, rush through the Stargate.
They find themselves in a large room, and at first they don't know where they are. Daniel sends the MALP back while the others explore the room. They find crates containing Staff weapons and an until-now unknown type of Goa'uld hand weapon, Zat'nik'tels, which they take with them.
Suddenly, there is a strong movement, and all the members of the team, except Teal'c, are thrown back. Upon Teal'c's instruction, the team attempts to dial Earth, but the Stargate fails to activate, despite the fact that it worked minutes before when the MALP was sent back. Hidden doors open and SG-1 hide as Jaffa march in. They bow before the Stargate as a large ball rises into the center of it. The Jaffa leave.
SG-1 soon discover that they have gated not to a planet but to a Goa'uld mothership which was in orbit of a planet. It launched into hyperspace towards Earth after their arrival, invalidating its Stargate's point of origin.
On Earth, Major Louis Ferretti is ordered to bring them back, officially for court-martial, but because the ship jumped into hyperspace, the coordinates are no longer valid and the Stargate does not activate.
SG-1 hides in the Death Glider bay and realizes they are on an attack ship headed to Earth. They also notice that Jaffa are heading to a gathering.
Sneaking back into the cargo room, they watch a large meeting in which they overhear Apophis state that they are getting closer to Earth before unveiling his son, Klorel, who is inhabiting Skaara, the leader of this ship until Apophis rejoins them.
They succeed in capturing Klorel, but Skaara is only able to assert control briefly, after one painful shot from a Zat gun (two shots kill). He asks O'Neill to forgive him for "what he is about to do," but before he can elaborate, the Goa'uld takes back control. When guards enter, they surrender rather than kill Klorel, who brings the two into the cargo room and contacts his father. Apophis is pleased, and orders Teal'c and O'Neill's immediate execution. When asked if there are other humans aboard, Klorel makes a typical Goa'uld mistake of overconfidence, declaring "I assure you, father. There could be no more."
Skaara seemingly exerts some influence, however, as Klorel disobeys his father's orders and delays their execution, bringing them to the Pel'tak (bridge) to witness the destruction of Earth, where they see the ship exit hyperspace near Saturn. Carter sets a timer on the C4, and she and Daniel try to free their friends.
Back at the SGC, Walter Harriman informs Hammond that Cairn Deep Space Radar has picked up two large blips heading toward Earth. Every branch of the United States Armed Forces is mobilized, and Hammond orders the Stargate Operations room converted to a command and control center.
On the way to the Pel'Tak, Carter and Daniel witness Death Gliders preparing for launch. They make it to the Pel'Tak and successfully take out the guards, but Klorel grabs Daniel, knocks the gun out of his hands, and uses a Kara kesh on him, intending to kill him.
When Klorel doesn't stop, O'Neill is forced to kill Klorel/Skaara.
Looking through the window, SG-1 sees Earth, and as the camera goes into space and pans out, a second ship is seen.
|Appearances for Within the Serpent's Grasp|
Teal'c: (at the fourth wall) If the coordinates are for a Goa'uld world which is not on the Abydos cartouche, the Goa'uld will most likely not expect us. I believe a medical attack could be successful.
O'Neill: Surgical attack, Teal'c. It's called a surgical attack.
O'Neill: (referring to a group of Jaffa) I always get a happy, tingly feeling when I see those guys.
Jackson: (staring at a huge floating sphere) Teal'c, What is this?
Teal'c: It is a Goa'uld long range visual communication device. Somewhat like your television, only much further advanced.
O'Neill: Ya think it gets Showtime?
O'Neill: (trapped on a Goa'uld starship) I suggest the two of you figure out how get us back home.
Carter: Sir, the only way to do that would be to turn this thing around and go back to where we started.
Jackson: Right, I'll just go tell the pilot...
O'Neill: (confronting a Jaffa) Hey! How're ya doing? Ah, seen a bathroom around here?
- This episode contains the only scene produced especially for Showtime, not shown on the syndicated versions, but included in the DVD release. When seeing a floating metal ball, Teal'c explains "It is a Goa'uld long range visual communication device, somewhat like your television, only much further advanced." In the Showtime version, O'Neill says "Think it gets Showtime?" In the other versions, Colonel Jack O'Neill says "Mmm... Goa'uld TV." Since Richard Dean Anderson is a fan of The Simpsons, the latter is one of many such in-jokes.
- Cairn Deep Space Radar, which detects the Goa'uld ships passing Saturn, appears to be a fictional part of the Deep Space Network. The Hubble Space Telescope and NASA, who get a closer look, are of course real.
- This episode marks the last appearance of Major Louis Ferretti, who first appeared in the feature film, though he is mentioned later in "Shades of Grey".
- Teal'c introduces Zat'nik'tels and how they operate. (This is one of the few uses of the zat-disintegration property before it is discarded by the producers.) Previously, the only Goa'uld hand-held weapons known to the Tau'ri (and the viewer) were the much longer Staff weapons.
- Skaara/Klorel were originally supposed to die in this episode when O'Neill shot him, however, after many fans expressed a dislike for Skaara's death, they used computer generating technology to put an image of Skaara/Klorel into a scene where he had not originally been filmed, making it appear that Skaara got off the Mothership safely.
- Assuming that Captain Samantha Carter's estimate of the length of the trip at 10 light-years is correct, and very generously assuming that SG-1 spent six hours on the ship during this episode, that would mean that a Goa'uld Ha'tak is capable of speeds up to at least 14,600 times the speed of light (possibly up to 87,600 times light speed if the trip only lasted an hour).
- This is the first appearance of hyperspace.
- At the 17:40 mark, when Captain Samantha Carter collapses her Zat'nik'tel, there is no sound effect at all. The same happens at 17:48 mark, after Teal'c disintegrates the Jaffa guard.
