Alice Roberts presents a round of fresh digs from the west of Britain, cutting between excavation sites as archaeologists narrate their own trenches on camera. The centerpiece is new work at Avebury, where evidence suggests the famous stone circle wasn't only ceremonial ground but a place people actually lived and worked, a finding that reshapes assumptions about nearby Stonehenge too. In Staffordshire, a team lifts a set of Iron Age gold torcs from the soil, the oldest gold objects found in Britain from that period, deliberately buried or abandoned around 2,500 years ago for reasons nobody has settled on. Elsewhere the film visits the camp believed to be a staging ground for Viking raids into Britain, tracing what the layout and finds reveal about how the invasion was organized. Roberts moves between sites rather than staying in one place, letting each dig supply its own footage and its own specialist voice, and the episode works as a snapshot of what British archaeology turned up in a single year.
