Dover 24/7: Britain's Busiest Port

Behind the scenes at the transport hub, following the people who deal with everything from raging storms and IT meltdowns to police emergencies and threats to life. Dover police are on high alert when a lorry driver claims he has a gun. The cargo team take delivery of a shipment of bananas, which totals a third of the UK's weekly supply.

A storm causes major disruption, a tug boat helps a ferry dock safely in the strong wind and more than 80 cyclists descend on the port for a charity bike ride. Meanwhile, the police find some suspicious-looking pigeons.

It's the start of the school holidays and a worldwide IT outage threatens the port's entire operation. The team members race to bring in the largest cruise ship of the season and police intercept a driver who's high at the wheel.

It's the busiest day of the year for Dover's cruise terminal, with three ships docking at once. The maintenance team go to work at the world-famous white cliffs, and the police stop a man who's wanted on immigration offences.

The engineering team rushes to fix a broken ferry berth. The police are out on patrol in an unmarked car, looking for drivers breaking the law. And it's a race against time to find a leak in the labyrinth of tunnels under Dover's white cliffs.

Major works are hampering the ferry terminal's operations. The engineering team race to fix the marina's broken gates - the gates that also stop the port from flooding. And the team welcome some very special visitors: the Children's Magical Taxi Tour.
