If you ever wondered what keeps a nation’s arteries flowing, Dover 24/7: Britain’s Busiest Port, airing Monday, June 23, at 8:00 PM on Channel 4, gives a straight answer. This episode puts the spotlight on what amounts to the busiest day of the year for Dover’s cruise terminal, a logistical chess match involving no less than three massive ships docking at once.

The series provides a look into the round-the-clock operations of the Port of Dover, a place where constant movement is the only constant. We see the wide range of staff roles and responsibilities needed to make this happen, from the teams managing passenger flow to the unsung heroes of the maintenance crew. This week, the maintenance team takes on work at the iconic white cliffs themselves, a reminder that the port’s activity stretches far beyond the docks.

However, it’s not all smooth sailing. The episode also touches on the less glamorous, but equally vital, side of border control. Police officers face the ongoing challenge of security, leading to one incident where a man wanted for immigration offenses is stopped. This highlights the daily pressures faced by port staff, who deal with both the practicalities of moving goods and people, and the more complicated matters of national security.
