Narrative for my Film

Rough Description of the Whole Films Storyline (only sections will be used for the trailer):

• Two children have been born roughly less than a year apart, sisters called Kida and Hael. 
• When Kida was born they noticed a birthmark on her arm but thought nothing of it. 
• The two girls grow up relatively normally, however Kida is occasionally violent towards Hael causing their parents to worry that it isn't normal behaviour. 
• Eventually at around the age of 6 Kida gets taken away to a children's facility in St Bernard's Hospital, Southall, for violent behaviour and vicious mood swings. The two main events that make this transpire is the fact that she tried to drown Hael in the bath and her mothers "accidental" death.
• Hael then grows up normally without Kida.
• When they reach age 18 Kida tracks down Hael and says that she has been released even though she actually escaped from the facility.
• They meet up and get to know each other, make up for some of their lost childhood together. 
• Hael finds out from her father Michael that their mothers death wasn't an accident, Kida actually pushed her down the stairs when she was a child. 
• It is then shown that Kida's birthmark has developed into some kind of symbol, which turns out to be the Mark of Cain.
• Her father and sister find out that this is the case and discover it appeared straight after she got sent away to St Bernard's and after their mother died. (when she committed a sin)
• As Hael and Michael have appeared back into Kida's life it causes the mark to make her violent behaviour worsen.
• Her dad and sister search wildly for a cure to the curse, they find out they can't physically hurt her either themselves as "therefore whoever kills Cain, vengeance will be taken on him sevenfold". 
• As this happens Kida's anger from the mark is directed upon Hael and Michael. 
• In hopes of hurting Hael she has an affair with her long term boyfriend Dean.
• The Mark of Cain takes full possession of her and she ends up killing her father and kidnapping Hael. 
• Due to the sisterly bond that they had as a child she doesn't kill her but instead forces her to relive their childhood and tortures her. 
• Eventually Hael manages to escape and call the police.
• By the time they track Kida down however she already taken her own life in order to put a stop to the curse, she can't cope with hurting the people she loves any more.
