Simon And Emily

Having committed countless sins in their misspent youth – Simon and Emily are paying off their debt by trading souls for the devil.
Working for a fallen angel, in an office full of similarly sinful people they're getting close to the target. Once they hit it, they can live the rest of their lives knowing that they'll be free from punishment when they eventually die.
Except that it was never going to be that simple. Just as they're counting down the last 70 souls a new man walks into Emily's life and the fate of the world comes into question.
With Simon's paranoia pushing them apart, Emily starts to consider:
"What if eternal love isn't quite so eternal?"
