Dover 24/7: Britain's Busiest Port

Police are on high alert when a lorry driver claims he has a gun. And the cargo team take delivery of a third of the UK's weekly supply of bananas.

When a massive storm causes chaos, a tug boat rescues a ferry in distress. And the police find some suspicious-looking pigeons.

It's the start of the school holidays and the port's IT has stopped working. The largest cruise ship of the season arrives. And police intercept a driver who's high at the wheel.

It's full on at Dover as three giant cruise vessels dock at once. Maintenance work starts on the famous white cliffs. And a man's detained on immigration offences.

Undercover cops hunt for drivers breaking the law. There's a leak in the tunnels under the white cliffs. And the engineers have their hands full with a broken berth.

With major works hampering Dover's port operations, the engineering crew get busy. And the team welcome some very special visitors on the Children's Magical Taxi Tour.
