I agree with much of what Nir Shelter has said. ?A interest-catching logline needs to layout the stakes. ?And the stakes would have to be really big to sustain a series. ?And the two biggest stakes of the time period ?would be the fate of the Queen Elizabeth and the Protestant versus Catholic rivalry for religious supremacy.

But from earlier posts, I gather that the die is cast in terms of the script. ?So rather than try to rework the setup, based upon what I can surmise, here is my go at what seems to already have been written:

A witch reluctant to use her powers teams up with a witch hunter with a conscience to save her family?from persecution only to stumble upon a conspiracy to overthrow Queen Elizabeth.

Or is it the case that the witch hunter is a coward, hasn’t got the guts to follow through with his religious conviction that witches should be burned at the stake? ?In which case the logline might be something like:

A timid witch teams up with a reluctant witch hunter to save her family from persecution only to stumble upon a conspiracy to overthrow Queen Elizabeth.
(25 words)

Whatever, the story seems to team up an odd couple?who start out to solve one dramatic problem only to discover “a mountain behind the mountain”, a greater dramatic problem with greater stakes that render her own problem petty and insignificant in comparison.

And I’m guessing the pilot ends on the cliffhanger beat of the discovery to hook viewers into coming back to find out what happens next.

I like the odd couple match up. ?I think this is the beginning of a beautiful friendship — with lots of conflict. ?Good luck with the project.
