A working stargate dating back more than ten thousand years has been discovered in North Dakota, on a Sioux reservation near Devils Lake.

The race to explore and claim the stargate quickly escalates, and those involved divide into opposing camps who view the teleportation technology either as an unprecedented opportunity for scientific research or a disastrous threat to national -- if not planetary -- security. In the middle of the maelstrom stands Sioux chairman James Walker. One thing is for certain: Questions about what the stargate means for humanity's role in the galaxy cannot be ignored.
