Your logline needs work, It reads awkwardly. Unfortunately, most readers will probably pass on the script because of it. I decided to take a quick look. I got to page four and couldn't continue.
The second page of the script was the deal breaker for me. The Stranger sets a house ablaze, yet, in the same scene authorities are there investigating? You didn't indicate a scene change, very confusing.
Your action lines make no sense. I wouldn't even consider them proper screenplay language.
I have never heard of a "heavenly armed" police man before. I assume you meant "heavily armed". Typos like this should be fixed before you even think of submitting anything.
Sorry to say, but the script is unreadable IMO. Keep writing. There is a ton of resources out there to point you in the right direction.
Best of luck with the writing.
