I presume he's looking backward over a span of 18 years.? Whatever, it needs clarification.
And as CraigDGriffiths said film is a visual medium.? What's the visual on ?"struggling with thoughts"??? And "struggling with thoughts" is a?subjective problem??not an objective goal.? And loglines are about objective goals.
The biggest problem with the logline is that it doesn't have a plot that promises tension and suspense.? The?story line seems to be?a?string of pearls, memories?strung together.??But a plot is not a string of pearls.? A plot is about a protagonist who wants something?looking forward in his life, wants to do more than merely reminisce looking backwards.? Who wants something bad enough to?pit himself against an antagonist and obstacles to obtain it.
