Frozen

A team associated with Stargate Command makes an astounding discovery - a perfectly preserved, apparently human woman who has been frozen since the Antarctic Stargate was first deployed. Then they discover she is still alive, and work to revive her. But her revival costs the team: they and SG1 succumb to a deadly disease the woman apparently carries. She can save them but not herself. And the effort exhausts her; she may not be able to save everyone before the disease claims her life. (imdb.com)
