Set in Northern Ireland during World War II, My Mother and Other Strangers follows the Coyne family and their neighbours as they struggle to keep life normal after a US Army Air Force airfield with 4,000 service men and women lands in the middle of their rural parish.

In the new episode, there’s a moment of joy when the Marsden’s Big Variety Playhouse comes to Moybeg for Halloween. The following day, the news breaks that a local child named Maisie Quinn has contracted Scarlett Fever. Rose has Maisie quarantined under Dr Black’s advice but when Maisie’s condition worsens, Rose turns to Captain Dreyfuss for help.
