To keep Americas Port as safe as possible, Dr. Geraldine Knatz and Chief Ron Boyd travel to Israels largest port, the Haifa, to see a recent innovation in counterterror technology, the Protector, a patrol boat that can be operated by remote control up to 10 miles away. Meanwhile, back at Americas Port, a tireless crew of tugboat operators guides an immense freighter ship into port. Ready to take action 24/7, eating and sleeping below deck for two weeks at a time, this team is always prepared.
