A TSA officer intercepts a firearm tucked inside a carry-on bag. Tensions rise as the passenger is questioned by the Miami-Dade Police Department, and they determine that he is neither a US citizen nor does he have a firearms permit. Meanwhile, the TSA intercepts a potential terrorist when an officer spots a knife deliberately hidden in the sole of a sneaker. A full-scale security response is issued to investigate in the premiere of this series, which documents the inner workings of Miami International Airport (MIA) and the people who keep it running.
