This says nothing about what HAPPENS in this movie. No stakes, no goals, nothing. For all you've told us, he saves Cupid and Cupid says thank you and gets back to what he was doing and that's the end of it.

What you have presented is the set-up to the story but not the story itself. The story would be what he does after saving? Cupid.
For instance:
------------------
"When a lonely security guard saves Cupid, he is granted one wish, but when he asks him to pierce the worlds biggest?supermodels heart, even Cupid might not be able to make that love connection happen."

Seems too long and disjointed. Don't use names.
Remember the basics: Main character, Event and his action in response.

Perhaps:

Cupid is the god of desire, erotic love, attraction and affection (Google Search Result)
If you can somehow relate THAT---to your protagonist's "dramatic need"---Since "Down on his luck..." doesn't establish the need (and thus role) of Cupid in his loveless life

Good Luck DackVigilante!!
