Following Kate's death, Nick struggles to adapt to life without his beloved spouse. With a full-time job and a newborn baby to take care of, it's the start of a painful emotional journey for Nick. His mother Ruby visits Aidensfield to care for Katie. As Nick returns to duty, the Ashfordly officers are caught in the middle of a violent feud between two neighbours that seems to revolve around a cat. Meanwhile, Greengrass' nephew proves more than a match for his mischievous uncle when the old scoundrel tries to cash in on his skills as a darts player.

When a young German man arrives to visit his father's grave, the residents of Aidensfield are outraged as his father dropped a bomb on the village during the war, killing two popular residents. Nick and Bellamy intervene when the victim's thuggish son sets out to avenge his parents' death. Meanwhile, Greengrass disappears after taking a hen-pecked husband on a drinking binge, causing panic in the village and a search party to assemble, whilst Maggie puts the past behind her.
