Well basically, Hazel was a happy child with a loving family until she died in an airplane accident before it was her time to die. When she woke up, she was inside the 'same' yet different airport where she had a ticket to first class seat on the next flight to high above (aka Heaven). However, being a kid who doesn't exactly understand the concept of dying, she desperately wanted to see her family again so someone suggested she go up to the counter and talk to the representatives. It was through talking to the representative that she got a grasp of what was currently happening and that when good people die, they will end up here in the airport with their ticket. And it is here that they could choose to wait till they see their loved ones. However, people without tickets are forbidden to enter this airport. In order to 'return' to see her parents, she could trade in her ticket and live out her supposed life span. The downside is that she could never return to the airport without her ticket. But another representative assured her that he could give her a ticket but only as long as she is able to fulfill her end of the deal --- that is, to curse (bind their soul destination to Hell) as many people as it takes to pay for the 'cost' of her ticket. Being the naive kid she is, Hazel accepted the second trade due to her desire to see her family. Here she is bestowed upon the power to curse people with voodoo dolls as well as given one white doll. The white doll is quite special since normally voodoo dolls need a personal item from the victim (ie. hair) and made in the likeness of the victim with a set of rituals performed before the curse can take place. However, the white doll could be invoked to kill the victim right on spot via hellish fire without any necessary items. However, that is only one use. And the user will experience the same amount of pain the victim receives. Before she left the airport, she was reminded that there were also other people with the same ability as her and that if she killed one of them, their victim count total gets added to hers.

It was too bad though, when she woke up in the 'real world' and faced the reality. One could say it was an 'alice world' or parallel world in which she was never born. Her parents thought she was someone's delusional lost child and called social services instead greeting her warmly. And to make things worse, she found out that her parents are adopting a child instead. In fit of jealousy and rage, she smashed the family photograph and ran out before social service got there. Thus begins her tale of hurt, betrayal, love and struggle to fulfill her end of the deal to see her family again, this time at the airport.
