The second in a three-part documentary series about the Port of Southampton. The pilots who guide large ships into Southampton, assisted by the marine staff on patrol and those in the control tower, are at the heart of making the port work smoothly. They are challenged by the danger of ships going aground and by dealing with leisure craft which frequently get in the way of the safest route into Southampton. Plus the work involved in turnaround day for a cruise ship, and a family on board spring a birthday surprise for dad.
