Intro. Final examination day of the novice police. John Nolan and Talia Bishop meet an incident at a bus terminal and find that the victim is linked to a terrorist cell about to release a biological agent in Los Angeles
All officers are mobilized to contain the threat. Officer Tim Bradford patrol with his newbie - and wife - Elena Bradford, a dedicated, brave recruit that faces the pressure of being trained by her husband
During the investigation of a exchanged backpack, the two enter a suspicious terminal. There, they find a sick, feverish and panting man. As they approach, the man collapses and coughing blood directly on Tim's face
Elena screams her name and runs to him, but Tim, already understanding what happened, gets staggers, pulls Elena by the arm and pushes her out of the room, locking the safety door between them
Elena (screaming outside): "Tim, open this door! You can't do that! Let me in!"
