I'm the Grim Reaper.

A woman in a dystopian future dies and doesn't remember her lifetime. She's in the line to get judged in Hell when Lucifer pops up and says he's a big fan of her work, and offers her a deal: reap sinners for him so she can still be in the world of the living and to delay her eternal punishment. She ends up working with a former detective who knows the criminal element of the city for her to reap people they think deserve it.

It's a great drama about morality, and how fucked up people can get in bad situations. Along with one of the best versions of Satan I've ever seen.
