In All Creatures Great and Small Season 5, it is Spring 1941, and we return to Darrowby to find young baby Jimmy keeping everyone in Skeldale House on their toes. Helen is getting the hang of motherhood with James away at RAF Abingdon, Mrs. Hall and Siegfried are enjoying having a little one around and Carmody is now a full-fledged member of the Skeldale family. With World War II now fully underway, Siegfried is taking up the slack at the surgery, Mrs. Hall and Helen are considering their contribution within the community, and Carmody is eager to step up. Siegfried is keen to have everyone back, but Tristan’s surprise return won’t be quite as straightforward as he hoped.

In Episode 1, a medical scare keeps James’ feet firmly on the ground and Siegfried and Carmody get their wires crossed over an animal. Meanwhile Helen steps in to help an old family friend and Mrs. Hall has a spot of bother when she decides to help with the war effort.
