Synopsis: When alternate realities collide, duplicate SG-1 teams arrive at the SGC. They’re facing great challenges in their own realities but it might not be possible to send them home. The “real” SG-1 soon learns that not all teams are exact duplicates — some of them are more desperate to save their worlds than others.
