Final ideas pitch

My group consisted of four members. We each discussed our ideas and then came to completly different ideas for our thriller. We presented three ideas to our teachers and narrowed our ideas down to one. Our idea was surrounding around a phycopathic teenage boy who shot up the schools pupils and teachers. The majority of the filming would be in an interview room with the killers girlfriend and her interegation of the account as to why she was not killed aswell.
