When their demon-hunting father goes missing, two brothers band together to find him and destroy the demon that killed their mother.

This logline feels like it focuses more on the characterisation of the father rather than the brothers, leaving me wondering who exactly is the focus of the story.

It feels a little like the characters have split goals: find their father and/or destroy the demon that killed their mother.

It's clear how he event (father goes missing) connects to one action (find father).

But it's not clear how destroying the demon that killed their mother is related to the event.
