I need an english-language annotation to send my short film to a festival.

I'm not a native speaker so please help to correct my mistakes and I will mention you in titles )

Here is the annotation:
"Deep inside an abandoned industrial area, in a bottomless pit lies unknown danger... This is a dream, that a jealous guy Ilya sees. His beloved girl cheats on him with his best friend. Or does she? What if that is only an illusion? And the scary dream is a reality?"
