Ruth faces a festive family crisis, Lenny considers the prospect of unwanted early Christmas leave and Zoe continues to enjoy a bit too much seasonal 'spirit'. As the competition for the fellowship continues, May gets frustrated by always being regarded the least-promising of the F2s and plays a trick on Lenny which has far-reaching consequences. Acting on May's misinformation, Lenny mistakenly tells two sisters that their father, Barry, has died and is severely reprimanded by a stressed and furious Adam. Could Lenny's Christmas leave be starting a little earlier and lasting a little longer than he would like? Ruth is looking forward to celebrating Christmas with a long-lost member of her family when she notices a family heirloom has gone missing from her flat. As she's plunged into a world of stolen phones, heroin overdoses and male prostitution, Ruth realises that she's likely to face Christmas alone. Will this mean she's ready to accept the support of ex-boyfriend Jay? As matters finally come to a head with Jordan and Adam over Jordan's role in the ED, Jordan is forced to face the music over his future as a doctor, while a stressed Zoe continues to escape the stresses of her life in the bottom of a bottle. Finally the staff find out who is responsible for the string of disappearances in the ED. Is there a thief at large or could it be secret Santa working in mysterious ways?
