The Ashfordly team are put under pressure to find the culprit to a spate of muggings. The only connection is that all the victims are middle-aged women who have recently visited the bank. Nick suspects two local thugs who were in the vicinity of the muggings, and Bellamy becomes emotionally involved in the case when his grandmother becomes the latest victim. Meanwhile, Greengrass competes with the Braithwaite sisters for ownership of their late father's sheep, which contains a stash of money, while Nick and Jo's relationship is once again threatened by her domineering mother when she falls ill and requires care from her daughter.
