Following the restoration of historic properties. This time, Dave is in Roker in Sunderland in the north east of England to help restore an iconic super structure - Roker Lighthouse and its 600-metre pier. This guiding light over Sunderland's harbour and its pier is in desperate need of an overhaul and builders are working hard to get it back to its original form. Inside the lighthouse, Dave discovers the perils of restoring a round building, climbs to the very top to polish its lantern and goes underground into a tunnel built to keep the lighthouse keeper safe when the weather got treacherous. On Sunderland's docks, Dave gets to grips with a monster crane and he puts his skills to the test as he prepares a get together with the mayor and Roker's locals to commemorate the opening of the lighthouse and its pier.
