The plot centers mainly around Georgia 'George' Lass. An 18-year old college drop-out who is at odds with her family and basically everyone. She takes on a dead-end job, and just wades through life in her own lethargic way. Disaster strikes and she gets hit by a toilet seat from the Mir station that was burning up in Earth's atmosphere.
Now dead she meets Rube (Mandy Patinkin), who is in fact a Grim Reaper (or Reaper for short). His task? marking those who are about to die so they can cross over and ultimately don't feel any pain when they die. George is now chosen to become a Reaper herself.
The weird part about this is that Reapers are undead. They walk among the living, some even have day jobs and 'live' their life while reaping souls.

The fun part is that they do not run around looking like the Grim Reaper at all, just normal people. The setback? The living see you completely different (aka different face).
I like this series so far because they show you what happens with George's family afterwards, and how George tries to cope. It's both dramatic at times, but there is plenty of comedy as well. One point of critique is about George herself. A friend of mine exclaimed that she would love to punch her, because she's annoying. Yes, she IS annoying, and at times she should get a smack to the head, but ah well xD
