Will these teenagers? unruly habits kill them? Or will it do enough damage to make them wish it did?

Are you planning to explore the teen's wish for death? Is this part of the plot? Does it need to be emphasized in the logline?

Your logline should ideally be
about someone
Who wants something
by doing something else
But something stands in their way.

An unruly teen
must learn to say no
to his gangland friends
before his way of life results in his death.

Or something like that.

Who is the main character?
What do they want?
Who or what is standing in the way?
