Okay, now that you've feasted, here's something about the show, straight from the SCIF*.com website:

When a secret base abandoned by the Ancients — the original builders of the

stargates — is found buried in the ice of Antarctica, the Stargate Atlantis

team is recruited for the most daring stargate mission yet: a one-way

expedition to the distant Pegasus galaxy.  There the Stargate Atlantis team

encounters a number of primitive human civilizations ... as well as The Wraith,

a sinister new enemy that threatens human life everywhere.

The Stargate Atlantis mission is headed by Dr. Elizabeth Weir, a specialist in

diplomatic relations. Her political savvy is balanced by the go-with-your-gut

bravado of her military counterpart, Maj. John Sheppard , a courageous and

gifted pilot. Rounding out the team are Lt. Aiden Ford , the enthusiastic young

officer who becomes Sheppard's second-in-command; and Dr. Rodney McKay,

a clever and quick-witted astrophysicist with previous experience at Stargate

Command. The team is befriended by Pegasus galaxy native Teyla , a beautiful

young leader among the Athosian people, with whom the Atlantis team forges

an uneasy alliance against The Wraith.

New faces join the Team this season. Most notable among them are Ronan

Dex, a human native to the Pegasus galaxy who has fought the Wraith for

seven years in defense of his planet. And from Earth comes Col. Steven

Caldwell , the commander of Earth's newest intergalactic battle cruiser, the

Daedalus.
