A NewEngland nurse finds herself in the center of a medical genetic ethics clash while caring for her patients – a story of modern medicine and another of ancient Mayan healing, unfold side by side, weaving togehter in this medical science fiction thriller.

I think two things would help improve this logline

First: Adding a goal for the lead character into the logline; what does the lead character want to accomplish?

Second: You should add stakes to the logline. You describe this as an adventure thriller, which implies there are steaks, but a ‘debate’ doesn’t imply stakes. What happens if the lead character loses the debate? (Whether an actual debate or metaphorical debate)

Anyway, when the lead character ‘finds’ herself in the debate, this should cause her to have a goal, and there should be consequences if she fails to accomplish her goal.

Hope that helps
