Timothy Spall and his wife Shane are back on board their beloved barge the Princess Matilda as they conclude their trip around the British coast. Tim takes on Rattray Head in the face of a huge storm. This is the equivalent of Land's End for Scotland and the point where they head south for the first time. The North Sea soon becomes the new enemy as he and Shane struggle to cope with this unrelenting force of nature. On land they find wonderful Scottish towns - Peterhead, Eyemouth and Stonehaven - but it's the town of Banff that resonates most. They fall in love with it and are sad to leave it behind as they pursue their odyssey of circumnavigating Britain. At the end of the episode they eventually reach the English sea border where they launch a message in a bottle.

Timothy Spall and his wife Shane are back on board their beloved barge the Princess Matilda as they conclude their trip around the British coast. The Spalls visit Northumberland, Newcastle and Hartlepool. Starting in Amble and the neighbouring town of Warkworth, Tim and Shane are in awe of this historic part of England as they visit the beautiful Church of St Lawrence and Warkworth Castle. In Amble, Tim meets a young sailor circumnavigating Britain in the opposite direction who, like Tim, was inspired to take to the sea after surviving leukemia. Next stop is Newcastle-upon-Tyne, a place he is truly fond of as he has been welcomed there ever since he played Barry in Auf Wiedershen, Pet. Along the way he meets actress Melanie Hill, who played Barry's first wife Hazel. Tim says that most of Britain saw Barry as a 'bit of a radish, a prannet', but that the Geordies thought of him as a 'sensitive character' and have always made him welcome. He takes us on a tour of his favourite places in the city. After Newcastle it's on to Hartlepool, which Tim discovers translates to Stags by the Sea. They soon find themselves trapped there after dramatically aborting a journey to Whitby whilst at sea. The North Sea once again reminds us that it's not to be messed with.

The Spalls are now in Yorkshire, and had been proudly steaming towards their final destination of London. But on the sea while travelling to Whitby, Tim is deeply troubled by strange engine noises. A failed engine at sea is incredibly dangerous so an engineer is called to Whitby to assess the problem. Tim is keen to see the town as this is where Bram Stoker based the opening of his novel, Dracula. Armed with his treasured antique walking cane once owned by Stoker, he finds the hotel where Stoker stayed and looks for the part of the coastline featured in the novel. Next is Scarborough where Tim filmed The Damned United. It's high summer and Britain's first seaside resort is crammed with holidaymakers. Arriving at Spurn Head they are now completely alone - there's no harbour or marina here, no town or access to land. They are moored to a single buoy owned by the local lifeboat crew and are waiting patiently for the perfect sea conditions to take them out of the north of England and into the south. It's a big journey - as well as the North Sea they have to watch out for heavy sea traffic, the turbulence of the Wash and dangerous sandbanks. In the dark of night arriving at the north Norfolk coast, a pilot boat guides them into the port of Wells-next-the-Sea. They soon discover it's a trip worth making as they explore this stunning coastline.

Six years ago, Timothy Spall and his wife Shane left London to tour Britain's coast. This final episode of their journey sees them complete their circumnavigation, but not before a dramatic and frightening twist. They arrive in Suffolk where they moor in Shotley marina, the site of the former naval training camp HMS Ganges. From here they venture into the serene Walton backwaters and then out into the North Sea for a trip to Brightlingsea, Essex. Essex to Kent should have been fairly trouble free. Tim filled his boat with friends, including actress Frances Barber, before setting off on this celebratory leg. Chatham is the port were the Spalls spent months learning the art of navigation before venturing out into the sea for the first time all those years ago. They know the area well, but Tim hadn't realised how much the waters of the Medway would change in the blackness of night. After hours at sea they are close to land, but soon become lost. The lights from all the factories and power plants on land add confusion and low tide increases the risk of running aground. After hours of fretting, Tim reluctantly calls the coastguard. The lifeboat crew take them to the nearest port, Queenborough in Sheppey. The next day they safely make it to Chatham, where both Tim and Shane are emotionally drained and relieved. The final journey up the Thames into London is where he eventually realises why he did this adventure in the first place - 'It's been a celebration of life and a spit in the eye of the audacity of fate trying to kill me, so we went out and tried to kill ourselves'.
