The speaker identifies himself as "Alar," and helpfully expounds his belief that this gate is a portal to the world of his ancestors.

Going on to say that his people are being a attacked by a enemy that will not listen to reason and that Urandan defenses are on the verge of collapse, he desperately asks for help. Then, the gate cuts out.

After the excitement is over, Sam goes over the logs and finds three impact events, which means that three people died hitting the iris, the barrier that Stargate Command has constructed to secure the gate.

Carter takes this gruesome news quite hard, even though O’Neill tries to explain that it is not her fault. Daniel decides the best way to deal with this crisis is to hit the books.

Hammond asks what kind of help they can offer. Jackson’s assessment is that this is a humanitarian effort, so food and medical supplies would be a good place to start.

Teal’c feels that a Goa’uld rouse would not be out of the question. Carter does not think it is a trick, especially after Jackson points out that the Urandans claim to be earth descendents. Another off-world activation moves the meeting to the gate chamber.

The lead gate tech informs Carter that retuning the gate should allow them to receive and send voice transmissions to Uranda. Alar again identifies himself.

Hammond tells Alar that he is considering his people’s request for aid. When Alar asks to come through the gate Hammond tells him of the iris and the death of his comrades.

Alar then treats the team to a video self-portrait -- a snowy black and white picture of Rene Auberjonois, Deep Space Nine’s Odo minus a lot of makeup and with significantly more facial hair.

He tells SG-1 they can see for themselves that they are indeed kindred. However, time is short -- although Uranda's weapons are superior, enemies still occupy most of the local land mass and a few more get through each day.

Luckily, Uranda's defense facilities are deep underground. While expanding them, Alar's people found the gate.

The bombing begins again and Alar restates his need for help, transmitting his planet's stargate coordinates and terminating the transmission.

Jack comments that the weaponry involved rules out the Goa’uld.

Daniel seems to think it is a foregone conclusion that Hammond will not help these long-lost kin of Earth and starts in to a lengthy diatribe, only to be cut short when the general tells him the team is good to go.

He explains to the group that SGC is not willing to commit the resources to turn a world war, but as Daniel pointed out there are humanitarian concerns.

After the meeting breaks up, Hammond pulls Jack aside and tells him this may be an opportunity to strike an alliance with an advanced civilization willing to trade technology that could help them against the Goa'uld.

He explains that he has already spoken to Washington and they have granted Jack authorization to negotiate.

Back in the gate room, SG-1 prepares to depart. They open the gate, send the MALP drone through and step across into a tunnel sorely in need of repair.

They find Alar injured on the floor. Carter looks after him when suddenly the local cavalry arrives. They seem ready to fire, but Alar holds them off by announcing that these people are their kindred from Earth here to save them.

After the entire group beats a retreat back to a more protected area of the complex, Alar gets some advanced medical attention and the team distributes the supplies they brought with them.

Alar seems slightly disturbed to see Teal’c, but welcomes him with Jack and Daniel’s assurances. Daniel asks Alar why they have not used the stargate to evacuate. In response Alar shows him a huge chamber filled with stasis tanks that hold the previous generation of Urandans suspended until the war comes to an end.

Later, Alar gives the team a tour of Urandan offensive capabilities, including remote fighters controlled via a VR-like interface from the war room.

Teal’c asks about ground attacks, to which Alar responds that the surface has been poisoned since the war began. When Daniel asks if there is really anything left to fight for, Alar assures him that it will not always be so on the surface.

An enemy recon drone approaches and the Urandans ask if one of the SG team wish to test the weapons systems they will receive in exchange for their help. Jack straps in the cockpit and takes it out for a very effective demonstration run.

When he is done he asks the pilot next to him if his performance was good for an old man, but the pilot only looks off with a far off stare. Alar helpfully explains that extended exposure to the interface can cause damage, but they are at no risk.

After the raid is over, our heroes and the Urandans celebrate their newfound friendship over a meal of Urandan yeast culture and military rations.

Alar makes a nice toast but takes notice when Teal’c does not join in, begging off because he "does not drink alcohol."

Dinner banter continues, with Alar and his friends explaining that they use controlled fusion -- a process that requires heavy water, which is in very limited supply. In return for a source of heavy water, they offer to teach the people of Earth how to create new weapons, medicines and power systems.

Everyone seems very pleased with the deal except Daniel, who asks what the heavy water would be used for. Alar tells him that they will use it to reinforce their defenses, and to strike back at the enemy.

Jack politely tries to cut Daniel off, but Jackson continues. He asks Alar why would they continue to fight a war that they could avoid by relocating through the stargate. Alar says this is their world, and if they left what would all of the suffering been for?

Just then another attack starts and the Urandans speed off to the war room. Left behind, Jack and Daniel have it out in private. Jack tells Daniel to shut up next time, then orders Carter to take the archaeologist back to report to Hammond.

Daniel and Carter continue the argument back on Earth as they walk into the gate room.

Carter tells the General of the deal Jack struck -- heavy water in exchange for all of the Urandan weapons, power and medical technology that appears to be a century ahead of current Earth standard.

When Hammond asks Daniel why he disapproves, Jackson explains his concerns that they are committing resources that could turn the tide in a war they know nothing about. He would like to know what the enemy is like and how the war started.

Hammond agrees and sends Carter and Daniel back with some fuel and questions.

Alar seems unhappy with the amount of heavy water, but is slightly calmed by the assurance that more is coming. He pushes off Daniel’s questions until after the attack.

In the war room, Jack and Teal’c help fly the Urandan remote fighters. Jack crashes his fighter into a bomber and before the video cuts out he sees people inside -- an alarming detail, seeing as how he was told the drones were unpiloted.

Later, the Urandans celebrate. In front of a national symbol, the elite gather under an old chandelier to toast someone's memory.

Teal’c asks who is this and Alar remarks that it is his father.

Toasting out of the way, Alar wants to get back to business. He would like substantial daily shipments of heavy water -- already, the deal seems to be showing some benefit, because the shield generator is running at full power.

Daniel asks how the war started, so Alar, in a talkative mood, tells a tale of a sneak attack and a childhood spent in fear.

The meeting breaks and Alar and Jack walk toward the gate and talk. Alar mentions that he would rather Teal’c not accompany them back because he "is not like us."

Alar leaves and SG-1 prepares to gate home. Jack pulls Daniel aside and, much to Jackson's surprise, apologizes. He says they are not going home -- he and Teal’c are going to poke around, and Daniel is to ask questions, lots of questions.

O’Neill and Teal’c check out the stasis chamber, where Jack discovers that all of the occupants are almost identical in coloration and facial structure -- blond hair, blue eyes, very "Aryan."

Daniel pulls the military commander aside and asks her about their enemy. She calls them "breeders" and says they come in all shapes and colors, apparently having "no respect for genetic purity."

Sam stays busy looking over the plans for the base. She notices that it must have been built a long time ago, before Alar says the war started. Furthermore, gas pipes run from the facility to the surface.

When pressed, Alar admits that his father’s vision was to wipe out the "breeders" covering the face of Uranda. He then demands the fuel, which Daniel and Sam refuse to procure.

A perfunctory attempt to hold the team hostage fails when Teal’c and Hammond use the drone fighters to escort the enemy bombers to the base.

The base is destroyed and the iris shut.

Hammond asks O’Neill if he was able to procure any of the Urandan technology. He tells the general, "no," but they shouldn't be sorry about it.

Carter looks on with a disbelieving stare as Alar dies on the iris.
