Episode 6

In this episode, lighthouse engineers battle a hurricane. The Corporation of Trinity House is the organisation responsible for managing and maintaining over 500 lighthouses and buoys that mark out the shipping lanes and warn ships away from the channel's hazards. The team on Trinity House's flagship, the Galatea, are called out to a damaged light vessel which is marking a hazardous sandbank in the Dover Straits. But their mission to tow it into harbour for repair becomes increasingly perilous when Hurricane Bertha closes in on the channel.
