Simple rule : event - character - action. No names, never, ever. It sounds like it would be interesting if Ben was the protagonist, because you don't want to write about two protagonists - especially as a newbie. So, why does Ben want souls? he's lonely? The deserving hell types are soooo predictable? This is Ben's story. If you changed his name to Stu you could call the screenplay Stu Alone.
Try this: "When a couple enter?Hell and turn ?heads because it was an obvious error, a lonely demon longing for better friends?notices their goodly people-filled rolodexes, so?he presents an offer guaranteeing redirection?to Heaven, but with a ?caveat because?they would have to deliver heavenly souls in a manner that would NOT make them?deserving of Hell."
A fantastic setup! It's a really long logline now - but you get the picture. It could be a comedy too.
