This clip comes from the season premiere of Continuum which aired last night in Canada.
This clip contain three scenes. In the first one, Kiera and Garza cooperate to escape from the Freelancers in an awesome fight scene in a stairwell. In the second scene Kiera and Garza double team an unlucky mook who is looking for them in the tunnels. In the third scene Kiera has a short fight with Curtis but she stops fighting back when she sees the universe is starting to collapse.
Just watched the full episode, really great start to the new season.
