Mike's past comes back to haunt him when his old flame Penny arrives claiming he is the father of her baby. To make matters a lot worse, DI Shiner warns Nick that two gangsters who Mike nailed in London have been released from prison with vengeance on their mind. Meanwhile, Greengrass falls in love with a poacher called Tessa Blundell, while Nick and Jo make big plans for the future, which could mean big changes at Ashfordly station.

It's the end of an era as Nick Rowan and his family prepare to leave Aidensfield for a new life in Canada. Nick's final case in Ashfordly begins when a villain who Blaketon once nailed shows up in the village and recruits his daughter and son-in-law to settle old scores. Meanwhile, Greengrass' latest money-making scheme is holding "ghost tours" in his "haunted barn" after hearing a story in the pub, and the old rogue also finds himself a new dog, whilst Dr Bolton sets his sights on taking over Kate Rowan's old surgery as he plans to win back Maggie.
