Test your logline here before spending months in development. This is not a contest, there are no prizes. However, you WILL get invaluable help in sharpening your concept and refining your logline. Make sure to start here.
Sent to infiltrate and subdue a tribe of alien natives in exchange for the use of his legs, a paraplegic marine questions his orders and must fight for the alien tribe’s survival in order to truly belong.
I really like this logline. It clearly describes the goal, the conflict and the protagonist. I haven’t seen the movie yet, so I might be wrong but the “in order to truly belong” bit seems a little vague to me.
