As the harvest ends, Stella and George Ellis follow their long-held tradition of hanging a corn doll to mark its close. But this simple ritual takes a darker turn when the doll mysteriously falls and a figure dressed as the mythical Cornman strikes. With their milk ruined and their hay set ablaze, the Ellises are pushed to the brink. Can Humphrey unmask the saboteur before their livelihood is completely destroyed?

Meanwhile, Martha and Humphrey embark on a new chapter as foster parents when Rosie begins her first day at Shipton Abbott Primary, while Anne takes a bold step to embrace life to the full.
