On their first underwater excavation, Tony and Phil help to identify a 16th century ancient ship that was wrecked some 400 years ago off Teignmouth beach in Devon, and use the joints on the beams to date a local pub as contemporary with the ship. Twenty years ago, a teenage scuba diver found a bronze canon belonging to the wreck on the seabed. But after all that time under water, will there still be enough of the ship left for the Time Team to identify it?

In a dig across nearly three miles of Irish countryside, the team find evidence of ritual and religious activity from the Bronze Age, Iron Age and the early Christian period. The fort of Emain Macha in Ireland was once the home of princes and kings of Ulster, and, according to Celtic legend, was built by King Conchobar, who also built two other palaces. The team go to Navan, the modern-day site of Emain Macha, in search of evidence of the other palaces and attempt to find a connection between what may have been a sacrificial pool and an ancient hill called Haughey's Fort.

Discover why for years a Suffolk farmer has gathered hundreds of pieces of Roman pottery, jewellery and coins from one particular field on his land. Where did all this rich material come from? The Time Team heads into Lavenham to find out. The hunt for the source of the farmer's discovery of Roman pottery leads to finds that indicate industrial activity such as kilns and metalworking. The team also enjoys a spot of experimental archaeology, trying out Roman methods of glassblowing.
