Zoey, RN and the ER Apocalypse

Working in an ER can be overwhelming but Zoey, being a nurse is only the beginning of her problems. She has to fight the demons coming through the plumbing possessing people. Then she was given a new reaper, Carl who not only has no real clue of what to do but would much rather light up a joint and play video games than help. As her problems continue to mount she also has to deal with Lucifer following her around like a love sick puppy. She is barley keeping afloat with issues when another demon has bigger plans, to kill her and take over the world.
Can Zoey prevent the apocalypse?
