Sanctuary

S1, E14: Engaged in combat the Atlantis team's puddle jumper is hit with an energy wave that leaves them unharmed but destroys their Wraith attackers. Hoping to find the source of the wave the team lands on the planet below. There they find a civilization enjoying the utmost health and happiness untouched by the Wraith. Their leader Chaya refuses to allow anyone other than her own people the sanctuary and safety from the Wraith that would be found by settling on their planet. Unwilling to give up so easily Major Sheppard (Joe Flanigan) asks Chaya to reconsider. After thinking it over Chaya surprises everyone by requesting to accompany them back to Atlantis to discuss the matter further leading the team to suspect they may be caught in a trap.
