The story is about a group of students who are studying to be doctors. They decide to find out what would happen if their hearts were stopped and
they died but were brought back after a few minutes. One by one they try it doing it for a little bit longer. They discover a place which seems
wonderful at first but soon they begin getting haunted while they are awake by sins they have commited. They discover the ony way to resolve
this is to say sorry or be punished for a while.
When I first begin to watch this it seemed to be a story about a couple of students having a good time but what I found was a horrifying representation
of what happens after we die and how we pay for our scenes. Most of the students crimes seemed rather harmless and so were their
punishments except for one of them who murdered a boy when he was young.
