Mean Dreams (2017)

Casey and her policeman father Wayne move to a backwater town where she meets Jonas. Soon the two are inseparable and daddy does not like it one bit. When Jonas is witness to Wayne being violent with Casey, he makes the decision to save her. When he sees his chance, he seizes it and they go on the lam.

This movie is fine, but it falls down at the reason. It's just "bad guy chases kids" -- but why is he bad? How has Casey survived so far? I don't need tons of backstory, but some would be welcome.
