(This does contain spoilers, but considering it aired 15 years ago you should have had time...)
OVERVIEW:
The weeks following SG-1's intense adventure keep the SGC busy as wave after wave of their new found enemy attempt to penetrate the Stargate's shield. Little does the team know, but someone has already gotten through.
REVIEW:
Personally I liked Enemy Withing, I thought that for beginning Stargate is was a good episode showing how the Gou'ld can infiltrate almost anywhere, no matter how many weapns you point at the Stargate, and also gave more light to how when it is required, Teal'c will do anything necissary to protect the one people who actually showed him trust and support. This reappears several more times throughout the series.
It was a little annoying that the infiltrator turned out to be Kawalski but only because he (Other than Daniel and Jack) was the last Alumni character from the original movie.
All in all, this episode is just another reason why Stargate SG-1 is a really great piece of work, from the writers room, to the actors. When it comes to O'Neill's humor or the serious but caring Teal'c everyone keeps the fun going and suspsense up.

Scott takes Lt. James with him, trying to play off the fact that they were having a “relationship” on Icarus Base. Before they leave, Scott asks the Senator to stay back and try to keep everyone calm. The teams leave, and Rush leaves right after, grabbing a bag and taking it with him. T.J. watches him leave, suspicious. 
Back on the ship, the teams are looking around for any threats or anomalies. Scott’s team encounters a door that seems to be locked. When Eli opens it for them, the see a giant greenhouse-type dome with a hole in it. 
The ship’s shield prevents explosive decompression, but the atmosphere begins to rush out. Eli closes the door quickly, and they decide not to try opening locked doors again. Dr. Rush walks into the control room suddenly and asks everyone to meet him in the Gate Room. He explains that the case he had taken contains Ancient communication stones, which will allow them to communicate with Earth. 
He also says that General O’Neill has put him in command, which no one accepts. Rush tries to establish control, but when the civilians begin to rebel, Scott takes command, telling the military personnel that Col. Young put him in charge, and asks everyone to head to the quarters that had been found.
When she mentions that he was locked up before they left Icarus, he goes off on her, and Riley has to restrain him. He gets called to check for any compartments open to space that need to be closed, and we see a Sergeant grab some protein bars and stuff them in his pocket.
Following, he runs into Eli, and finds out that the ball is actually a floating camera manufactured by the ship. Eli calls it a “Kino”. 
Meanwhile, Col. Young finally wakes up, but he’s not in the best condition. He can’t move his legs. T.J. hopes it’s just temporary, but they have no way to know for sure without a little time.
The scrubbers are shot, and CO2 is going to build up in the ship to lethal levels. They throw around some ideas on how to replace the scrubbing compound, but they don’t have anything to replace it. 
Rush tries to close the inner shuttle door, but it must be closed from the inside, meaning whoever closes it will die. T.J. explains the situation to Young, at the same time that Chloe explains it to her dad. Unless they get the door closed, they have just over an hour till they run out of air. Rush finally states the obvious, someone will have to sacrifice themselves to shut the door. 
Knowing that they probably won’t get any volunteers, Rush goes over the list of people on the ship. Scott and Chloe both say that you can’t ask someone to go and die, and Rush counters with the fact that unless someone does close the door, everyone is going to die.
It turns out Chloe told him what’s going on. Scott calls to Greer, warning him that the Senator may be on the way. He’s already there, and he has a gun. When Franklin can’t close the door from the outside, Senator Armstrong enters the shuttle and closes the door.
Rush is apologetic, saying that her father has given the rest of them the chance to survive. 
Eli is also grieving, and Rush shares some information with him to help him. Rush has discovered that they name of the ship they are on is called Destiny.
The Ancients has launched it thousands of years ago, planning to board it using the Stargate. However, they ascended before they did, leaving the ship to fly on unmanned. 
An alarm sounds, alerting Rush to the dialing. He hurries to stop them, telling them that the ship “simply doesn’t have the capability to dial Earth.” 
In the middle of his explanation, Destiny drops out of FTL. Rush believes that he has managed to tell the ship their problem, and that the gate should begin dialing to a planet with the resources they need. 
When they find out the planet is habitable, Young decides to send a team through to look for anything that can be used to scrub CO2. They also notice that there is a countdown running, with just over 12 hours till it runs out. Rush believes at that time, the ship will jump back into FTL, leaving whoever is on the planet behind. 
Rush and Young choose Franklin, Palmer, a Marine escort, and Eli also volunteers to go. They all gear up, and head through the gate. Rush stops at the event horizon and looks back at Young one last time. 
Young nods to him, and Rush steps through the gate.
