Following the death of Sarah-Jane Smith, her friends and allies reunite at a memorial service to pay their respects.

Luke and Sky must help the Skullions, but Sarah Jane is in danger too, so who will they save?

Joseph Serf has launched his new SerfBoard, the must-have computer that no one can resist owning. Intrigued, Sarah Jane takes Luke and Sky to investigate what is so compelling about Serf and his business. Meanwhile Clyde and Rani take a SerfBoard to pieces, suspecting alien technology may be the answer. Everyone wants the new SerfBoard - and why not? What could be so dangerous about a computer?

Clyde is living on the streets of London, lost and abandoned - and hiding from the Night Dragon. 

The world has a brand new Public Enemy Number One - and his name is Clyde Langer. 

Metalkind fights Fleshkind for control of Sarah Jane's new friend, Sky. Can Sky stop herself destroying the world?

Sarah Jane finds a baby girl on her doorstep and tries to find out who abandoned her. At a nuclear power station, a beautiful woman appears out of thin air and uses alien powers to take control. She's looking for something - and realises that Sarah Jane may just have it.

A celebration of the Doctor's greatest companion, adventurer and time traveller Sarah Jane Smith, played by the late Elisabeth Sladen. Contributors include David Tennant and Matt Smith.
