I am looking for a television show that I saw in 2013

In one scene there is a woman in a red dress with blond hair sitting alone in a pitch black room that vanishes.In another scene a man uses lockpicks or keys to unlock a door while standing next to another woman that panicks.In another scene a man and a woman encounter a room with racks of weapons.In the end credits a person is talking and says whoever is watching us is definitely testing us.
