The team are in central London near Vauxhall Bridge where, at low tide each day, the Thames reveals the tops of a mysterious group of prehistoric timbers buried on the shore. Tony Robinson and the Team have just two hours a day of frantic digging and fighting against the tide for three days to excavate just one of these strange timbers to discover its significance.

The small Lincolnshire town of Ancaster lies on Ermine Street, which is a major Roman road heading north from London. The only Roman remains visible today are some massive earth banks and ditches, which have been dated to the 4th century. So what was here before these defences and why were they built?

The pupils of Ancaster School in Lincolnshire have assembled enough Roman finds to start their own museum. But the story of their town, which straddled the great northbound road, Ermine Street, has never been told. Tony Robinson and the team investigate why a huge town wall was thrown up in the Third Century, search for the likely location of a pagan temple - and uncover the remarkable secret of an old man buried nearby in the Third Century.

The team investigate an encrusted cannon, a huge anchor and a remarkable collection of rare 16th-century pottery including a beautiful jar scattered amongst the seaweed on the seabed just off the West coast of Scotland.

Battling the sea and the weather, Tony Robinson and the Team work with RAF divers and specialist underwater archaeologists to salvage what they can of the wrecked ship. It's certainly a Mediterranean vessel but the key question is: could this be one of the lost ships of the Spanish Armada?

The team are invited to the Military Intelligence base at Chicksands. Under the watchful eyes of the guardians of one of the RAF's most secretive bases, Tony Robinson and the Team have just three days to investigate a most unusual 13th-century monastery. Gilbertine monasteries housed not just monks, but nuns as well. Strict rules kept them apart, except for the odd scandal of course.

Near Ironbridge Gorge in Shropshire the team set out to find the remains of an eighteenth-century blast furnace for smelting iron. The team digs up a pub car park. In the cellar of the pub lies the opening to an 18th-century blast furnace. Was this village one of the places that led the way through the technological changes that transformed Britain and made the area the heart of the industrial revolution? Under the watchful eye of the landlady, and aided by a few pints, Tony Robinson and the Team waste no time in their quest.

The team investigate Cornwall's most important Iron Age site. A farmer has a houseful of Iron Age finds from a huge field overlooking the Helston River. It is clearly an Iron Age enclosure that has been fortified, but it is so large that its purpose is a mystery. And to make the task even harder there's another fortified area nearby. What was going on here 2000 years ago? Can they solve the riddle?

The team explores a disused RAF bomber base, which is designated as a mass burial site for cattle in the foot and mouth epidemic. But before the diggers move in a government geophysics survey finds the site to be a dense Iron Age or Bronze Age settlement. The archaeologists discover a string of mysterious circles, trackways and enclosures. All this points to a huge undiscovered prehistoric site. Time Team is invited in to investigate. Will it turn out to be a Bronze Age burial site or an Iron Age village?
