[spoilers] Episode 1 Summary

[JHyde]

Stellar work Silktie.

Spoiler: show

The pictures posted today would seem to indicate Ruth and Harry are being held in the same place.

My summary of plot:

Ruth calls MI5. Ros is apprised of the situation with her 'family' and the Iran backstory. Ruth arrives on the Grid just in time to see the film of Harry's execution and his captors demanding that if Ruth does not deliver herself to them her 'family' will also be killed.
Ros does not believe Harry is dead. So to save Ruth's family and Harry Ruth is rigged up and sent in to infiltrate, but the team cannot simply track her in as there is still information needed before they storm the building. This happens, they get home safely.

Ruth and Harry still love each other but that love is a liability. So they are understandably reticent about jumping right into things. I think it will take a few episodes to hook them up.
