Story line idea

We have been thinking of possible story lines to continue our movie. it would have to relate to our genre of mystery and thriller .

At the moment the story is, 3 teenagers are messing around in a park when one goes missing on her way home. she doesn't turn up for 2 days at school so her friends gi ti her mums house only to realise that she hasn't turned up there either. they then go to the police and give in their witness statements however this all took place on 15th December 2015. This is why  private investigator is working on the case as the police wouldn't carry out a case for this long.

We have one idea where the missing persons mum was tired with the police work on finding her daughter and she comes t o a conclusion that they're not doing a good enough job so she searches elsewhere for someone to take her case. she in the end hires a private investigator to take over. This is the reason behind him pinning information from a case that happened a year ago. she found him online, he was very expensive but had the highest success ratings in completed cases so she hired him. the one thing she didn't know is that the private investigator is a 17 year old boy. This gives a sense of dramatic irony as the audience are the only people who know his age.
The movie would then continue on with us following the boy in his 17 year old life and his hidden life, trying to keep his online identity as a secret.
We still don't know if the daughter is found but during our opening we mention that she had problems with her dad which could be a main lead.
