Jonathan is a young man with a strange condition that only his brother understands. But when he begins to yearn for a different life, their unique bond becomes increasingly tested.

Ba'al travels back in time and prevents the Stargate program from being started. SG-1 must somehow restore history.

The Doctor and Clara face their Last Christmas. Trapped on an Arctic base, under attack from terrifying creatures, who are you going to call? Santa Claus!

Inspired by Chris Marker's iconic 1962 featurette La Jetée; the year is 2073—a not-so-distant dystopian future—and the setting is New San Francisco, the scorched-earth tech-dominant police state where democracy and personal freedom have been well and truly obliterated.
