Lead by Captain Jack Harness, Torchwood is a research-defense force independent of the Equestrian government, founded to defend pony-kind from dangers inside and out, and to investigate the impossible and surreal.

The Royal Wedding draws near and Canterlot is faced with an unknown threat. Following a mysterious attack, Torchwood and its allies hunt down the mysterious assailant. Meanwhile, Jack is plagued by memories believed to have been erased a long time ago.

Is there a connection between these events? Or is it mere coincidence?
