With the raging fire from her grisly past illuminating and burning everything she has worked hard for, the troubled young girl embarks on a difficult journey to find healing and closure.

Agreed with Richiev.

Good loglines are made up of clear detail that describe a plot. For example "...a difficult journey..." is a generic term as it contains no plot specific detail. The descriptions you use in a logline should inform the reader enough so that he or she understand the MC will undertake a difficult journey instead of literally wording it in the logline.

Not sure what this logline means.

You should give us a specific event in the logline and a specific goal.
