When a problematic medical student, on probation, discovers a plot to kill the imperial family and overthrow the current galactic dynasty, he offers his services to the mastermind terrorist and falls in love with his daughter while trying to undermine his plan.
Currently, this is just a long way of saying the inciting incident which (as Richiev) has pointed out, is just the discovery of this plot. What happens next?
Why is he disgraced and what bearing does that have on the story? Why is it relevant that he is practicing trans-species medicine? At the moment, these are unnecessary to the story – as I understand it from this version of the logline. If they are really important then make sure we understand why.
Hope this helps.
