Stargate Atlantis Season 1 Episode 3: Hide and Seek



Eager to experiment with new technology, Dr. McKay volunteers to be Dr. Beckett’s first patient for his new ATA gene therapy. Now able to use a personal shield emitter, McKay recklessly tests its properties, only to find that it could lead to his death. Elsewhere, a “living shadow” entity threatens the city after it was accidentally released from a container where the Ancients were studying it. It roams the city looking for energy to feed on, and the more it feeds, the more lethal it becomes.
