When bushwalkers get lost in the mountains they must resolve the tangled web of their own relationships and battle a spider man to survive.
As mentioned above there are two goals stated in the logline resolve the relationship problems and defeat the Spiderman.
Which is the A plot goal?
Make the logline about that and that alone as a loglein needs to describe a single plot.
Better to define who gets lost to aid the premise: After a couple gets lost in the woods…
Also be carful of using a known character in your logline such as Spiderman unless you are writing for the franchise.
Hope this helps.
