Atlantis at risk in ‘The Intruder’

New plot details have arrived for “The Intruder,” the second episode of Stargate Atlantis‘s new season!

Beware of spoilers below.

“A mysterious intruder has infected the Dadealus’s computers with a virus that may allow them to take control of the ship.

“When a scientist is killed in the Daedalus’s computer room, McKay (David Hewlett) first believes the poor circuitry is at fault. However, when another scientist is killed while investigating the death, McKay begins to suspect that someone — or something — is deliberately planning these breakdowns.

“Soon after, McKay is alerted to a virus on one of the ship’s computers. When he runs its code through a translator, he is shocked to discover that it is written in Wraith. Even worse, he learns that the virus has the ability to re-write itself, making it seemingly impossible to conquer. Realizing that the program’s capability to mutate has virtually given it a mind of its own, McKay worries that the Wraith may use the virus to take control of the ship — with potentially deadly results.

“As feared, the virus’s artificial intelligence soon takes control of the Daedalus’s auxiliary ships, and the crew becomes increasingly powerless to defend themselves. Fearing that the Wraith will use the Daedalus’s advanced features to attack Atlantis, McKay and Sheppard (Joe Flanigan) race against the clock to counteract the virus before the Wraith turn the Daedalus’s advanced technology against the city.”

“The Intruder” airs Friday, July 22 on The SCI FI Channel in the U.S. Read more in GateWorld’s Stargate Atlantis episode guide!
