What experience and training does the overprotected teenager have in rock climbing at the time she hooks up with the older rock climber?
A logline is a concise statement of a plot.? One and only one plot.
This logline has two plots.
1}Inciting incident: the teen hooks up with the rock climber.? Objective goal: With his help , she climbs a dangerous route.
2] Inciting incident: They witness a murder.? Objective goal: Survive a homicidal maniac.
The first plot could fill out an entire film by itself.? Such are the challenges of rock climbing. (See "Free Solo" and "The Dawn Wall".)? The 2nd plot seems to be literally and metaphorically overkill.? Contrived overkill, at that.
What do I mean by contrived? A major problem I have with the 2nd plot is that it comes out of nowhere, seems totally disconnected from the 1st plot. It isn't necessary that the only place and time in the whole world the couple could possibly witness a murder is while rock climbing.? They could just as well have witnessed a murder coming out of a 7-Eleven, or driving down a road, or walking in a park.
There is no cause an effect relationship between the 1st plot and the 2nd.? There is only coincidence.? They happen to be climbing -- and lo! -- a? deux-ex-machina event falls into the narrative.
Also what is the thematic connection between the 1st? plot and the 2nd?? A film should be united not only in a singular plot line but also in a singular theme or controlling idea?? What is the theme or controlling idea shared by both plot lines?
