This is it, the last episode of the season for Poldark and the gang, but don't worry, the BBC has already confirmed it will return for a fourth season. In tonight's finale, Sir Francis places Ross in charge of a group of volunteers to defend the Cornish coast after Prudie and Tholly catch sight of French ships on the horizon. Elsewhere, George returns from parliament and is outraged to discover that Drake is living in the smithy on the edge of Trenwith land. However, Tom Harry is only too happy to take on the task of making sure he does not remain there for long. Also, Emma struggles to reconcile her feelings for Sam with their religious differences, and Hugh continues to court Demelza in secret.
