Nick is a veteran on Montreal's urban police force and has just returned from a three-month leave following the traumatic shooting of his partner. On his first day back, he is unhappy to learn he has been partnered with Ben, who has just transferred from a small town to restart his life in the big city. Both men are good cops, who deeply care about the job, yet struggle to move beyond painful events in their past. Ben and Nick must attempt to put their differences aside as their lives further intertwine, both professionally and personally, and continue to take surprising and dramatic turns.

Atlantis, built thousands of years ago by the highly evolved Ancients, is home base for an elite expedition from Earth. These courageous military commanders and scientists leap through the city's Stargate to explore the wondrous Pegasus galaxy and battle the treacherous Wraith, who seek control of Atlantis -- at any cost.
