After discovering his sister, presumed dead, is alive, a soldier must betray his father, the general, to save her.

Number of words in logline:- 19 (if my math is right)
Working title:- Betraying Blood (but it’s got the word ‘blood’ in it, which makes it sound gorier than it is. Suggestions are welcome!)

Also, background information in case you need it:?
This is a fictional world. There are humans and elves. The two races are on very tense relations with each other. The soldier is a human (his father is too).
