Stargate

An interstellar teleportation device, found in Egypt, leads to a planet with humans resembling ancient Egyptians who worship the god Ra.

A secret military team, SG-1, is formed to explore other planets through the recently discovered Stargates.

An international team of scientists and military personnel discover a Stargate network in the Pegasus Galaxy and come face-to-face with a new, powerful enemy: The Wraith.

Trapped on an Ancient spaceship billions of light-years from home, a group of soldiers and civilians struggle to survive and find their way back to Earth.

Ba'al travels back in time and prevents the Stargate program from being started. SG-1 must somehow restore history.

Young Catherine Langford embarks on an unexpected adventure to unlock the mystery of what lies beyond the Stargate in order to save the Earth from darkness.

SG-1 search for an Ancient artifact called the Ark of Truth to finally defeat the Ori. However, the Ark is in the Ori's galaxy.

In the near future, a veteran of the Stargate program, four cadets, and a mysterious alien are prevented from returning to Earth by a impostor. The heroes must use the Stargate network to find another way back home while keeping one step ahead of their enemies.

As the Goa'uld attack fleet approaches Earth, all four members of the SG-1 team are taken prisoner. They get help from an unexpected source when Bra'tac, Teal'c's mentor, reveals that he is on board. Apophis has delayed the attack until his son Klorel is revived, giving them some time to prepare. SG-1 has used all of the C4 on one of the two ships but must find a way to dispose of the second. Back at Stargate Command, Lt. Col. Bert Samuels arrives as a Pentagon liaison officer but also reveals a new weapon they have developed. General Hammond is dubious. They begin to transport humans to an Alpha site in order to ensure the continuation of mankind.

O'Neill, Carter and Jackson are trapped on Hathor's planet. Teal'c and Hammond go to Chulak to forge a rescue plan and recover the team.

SG-1 has to deal with a Replicator infestation on a Russian sub on Earth while Major Carter advises the Asgard about combating the menace in their galaxy.

Stranded in another galaxy while fleeing their attack on Apophis' fleet proves only the beginning of SG-1's problems as multiple enemies appear.

Master Bra'tac arrives with bad news: Teal'c's wife is deathly ill, and Teal'c leaves to be with her. Shortly thereafter, the gate is opened but nothing comes through. Then Carter discovers a very low power signal that is slowly building an overload powerful enough to destroy the Earth.

A group of nomads on an alien planet find Daniel Jackson naked in the middle of ruins and take him in. Jonas translates the tablet Daniel said was important and discovers that it describes the last city the Ancients were building before the plague. He surmises that the list of addresses Jack put into the computer while storing the Ancient data were Ancient outposts in temporal order. Thus the last of the addresses should be the "City of the Lost". SG-1 visits the planet and happens upon the nomadic people, now inhabiting the ruins of the Ancient city. There they find Daniel, but discover his memory is gone. They must recover his memories in order to discover the secret to defeating Anubis.

In a last ditch effort, O'Neill activated an Ancient weapon in the Antarctic to defeat Anubis. With Jack still in stasis in the Ancient outpost buried in Antarctica, SG-1 tries to contact the Asgard. Meanwhile their new leader, Dr. Elizabeth Weir, tries to decide what to do about a request for peace talks from the Goa'uld System Lords.

With a new commander of the SGC comes a new leader of SG-1, Lt. Col. Cameron Mitchell, a former fighter pilot who flew an F-302 in the battle over Antarctica. However, he is deterred by the fact that all the other members of SG-1 are leaving for other ventures: Teal'c to manage the Jaffa Nation, Carter to Area 51 for alien R&D, and Dr. Jackson to Atlantis as an Ancient expert. Mitchell endeavors to keep the members of SG-1 for himself, but they are increasingly tough to convince.

As the Ori invasion continues, Vala and Daniel must deal with their leader, Vala's young daughter, who is rapidly aged by the Ori to serve their purposes.

The Daedalus arrives and the two hive ships are destroyed. Atlantis seems saved, then Zelenka detects 12 more ships. Ford seems changed after a fall in the water.

Fallen into the Wraith trap, McKay initially resigns to fatal captivity in a cocoon, but Ronon keeps struggling to attempt escaping, or at least taking some Wraith down with them. Sheppard managed to hide his glider on the very hive ship, seeking a way out, surprised to get radio contact with Michael, who seeks revenge after the ingrate queen has him semi-restrained as 'too human' suspect. While they try to sabotage the hive and maybe escape, the Daedalus and Orion race just in time to fight the two hive ships before they may attack earth. Weir is summoned to SGC for a pointless grilling by the International Oversight Advisory, finding them bureaucrats unable to risk a decision beyond questioning what was already done. So she returns, never mind the career risk compared to a Wraith culling. Sheppard manages to reach the Daedalus and his party comes up with a daring plan to overpower the hive with the weaponized retrovirus, despite bombarded damage compromising even their life-support systems.

With a damaged ZPM, and diminished hopes of survival, the Atlantis team finds themselves stranded in the middle of empty space with hardly any time before they run out of power completely. Dr. McKay is challenged to the max as he tries to find a way to save Atlantis from its doom. Meanwhile, Dr. Keller races to treat Weir's increasing head injuries, but the only answer she can come up with could have grave results for everyone on board.

Combat engineers from Atlantis work against the clock to rescue four of their colleagues who are now trapped in the rubble of Michael's medical compound. With Michael en route, they quickly locate McKay and Major Lorne but Sheppard and Ronon are far deeper and their rescue is not assured. When Michael's ship arrives, they decide to try to rescue Teyla who is in labor and close to giving birth. When it's all over, Col. Carter is recalled to Earth for a performance review but Richard Woolsey has some bad news for her.

The Lucian Alliance is still in control of the Destiny and Col. Young is determined to get it back under his control. Young and most of his personnel are prisoners, however, leaving it to Rush, Lt. Scott, Sgt. Greer, Eli and Chloe to find a way to get control of the ship. They are left alone on the Destiny when Young and the prisoners are dispatched to a nearby planet. When they take possession of the control room, Rush devises a plan that will likely result in the death of the Lucian Alliance members but also any of their colleagues that might still be on board. Meanwhile, TJ is unconscious recovering from her wounds but seemingly awakes in a perfect dream where she and her newborn are joined by crew members from the past.
