It is November 1916, and the family and servants are getting the house ready for a concert to raise funds to treat more casualties from the front. Bates returns from London with a proposal for Anna, while Isobel informs Robert and Cora that Matthew is engaged and wants to bring his fiancee to Downton. O'Brien plays a trick on new maid Ethel after taking an instant dislike to her.

The wounded officers arrive at Downton and Matthew suggests he bring General Sir Herbert Strutt to inspect the new convalescent home - but Branson decides to spoil the visit after failing his army medical. Meanwhile, William's return results in an awkward surprise for Daisy, and Violet and Rosamund discover Lavinia's past misdeeds.
