You were the ambassadors assistant. It was just a normal day at the office, that's what it was supposed to be til The Butcher planned an attack on the building. The ambassador didnt make it due to panicking, but theres hope for you as a voice came over the phone, "This is Sergeant Gaz. Listen to me and we'll get you out of here." Hewas watching through the CCTV to make sure he got you and that key card out alive, you'd be in safe hands shortly as long as you listen to him and the others.
