Rising (Stargate Atlantis)

Stargate Atlantis Episode 1/2 ("Rising")

Synopsis

After opening the one way gate to Atlantis in the Pegasus Dwarf Spheroidal galaxy, the new expedition team, led by Dr. Elizabeth Weir, is faced with many pressing problems. First, while the submerged city is protected a shield, the city is low on power and may soon be flooded by seawater. Second, the part of the team sent to find new energy sources and possibly a backup location, while meeting with friendly native humans, is attacked by a new enemy that is known as the Wraith. Several members of the team are taken by the Wraith, including the leader of the expedition team's military branch, Col. Marshall Sumner (guest starred by Robert Patrick), while the remaining team member retreat to Atlantis, together with the natives.

When the shield threatens to collapse completely, the autonomous city soon surfaces, somewhat alleviating the power situation, but still leaving the city defenceless without a shield. Using an Atlantean spacecraft, the team soon attempts a rescue, led by the second ranking military officer, Maj. John Sheppard. Most of the taken team members and native people could be rescued, but it was too late for the original leader of the military branch. Now joined by the native people, the expedition crew establishes a foothold in the Pegasus galaxy.
