On the eve of the year 2000, a homeless street beggar struggles to stay afloat in life seeking a place to rest his weary soul while a drug-addicted Sydney paramedic responds to a call that will forever change both of their lives.

The premise in your current logline = A homeless person tires to finds a place to rest while a drug addicted paramedic responds to a call.

-- No direct causal link, forces me to hazard at guesses to how they relate, which doesn't mean "Send me that script -- I have to know how they could possibly relate..", but "I can't see how they relate, so I don't care...so lets pass on that one...got any others?"

Versus --> "...the story of an estranged father and a daughter coming together under the most unlikely circumstances bringing closure on their relationship."

Whilst the latter is not sufficient for a logline, it's telling me more about what this movie is about -- it's the meat of the story, the most important part -- that's what needs to be incorporated in the logline, imo. This is potentially juicy stuff which has the potential for a feature -- in fact, if you haven't written it yet, I find it hard to see how you would manage to fit it into a short -- sounds like you would need a good chunk of set-up... I know I'd struggle -- but maybe that's just me, king of verbosity ;)

Anyway -- best of luck again.

It's both of their stories, they intertwine with each other coming to a conclusion, both of them have battled with a darkness (yes, abstract but that's how I do, I understand conventionality but I'm a fan of difference) so I could include the antagonist as the darkness (which you do see) but the story is of an estranged father and a daughter coming together under the most unlikely circumstances bringing closure on their relationship.

You've described two protagonists - not a protag and an antag - and so your logline is bloated. Whose story is it?
