Short film plot and narrative plan

My Short Film Plot:

The basis of my plot is a group of teenagers bored and looking for something to do. Following a cliche, I decided that their evening would be based around wanting to go somewhere and get drunk but they are all underage therefore have nowhere to go. Running out of ideas, one of their friends is able to get them alcohol so they just needed a place to go for the evening. Their parents do not approve of them getting drunk as they think it is irresponsible and do not want them to get into a state. The children each tell their parents they are going to each others houses when actual fact they decide to find a secluded area and make a party of their own. They find an abandoned plot of land whilst intoxicated and decide that it would be where they stayed overnight. The next morning they wake up and have no recollection of how they got where they are and where one of their friends has disappeared to. One of the teenagers wakes up with blood on their hands and an empty alcohol bottle nearby, it was time to investigate what happened the night before. Whilst searching the building there are strange items in the rooms that they look in like hand cuffs and gas masks. This adds to the atmosphere of confusion and panic as to where they are and what usually takes place within the building. Their phones are either dead or have no signal so calling for help or tracking where they were seemed unavailable. They then stumble across the lifeless body of their missing friend and scream in panic. It is assumed that it is one of them who had done it because the building appears to be deserted and empty besides them. They panic because they need to get help but don't know how to explain their situation. A police siren sounds. The remaining teenagers sprint away from the building immediately before they can think about what they are doing. They have no alibis because they had each told their parents that they were staying at their friends houses and there was nobody else in the building that had seen the events of the night before. The camera at this point will go back to the point at which the body was found and it has disappeared. When the camera turns to look around to see if anyone is there, the lights cut out...

Disclaimer:

Although alcohol is present in the story line it is not the main element of the plot. There will be bottles used for the effect of the teenagers getting drunk but inside each of them will be fruit juice/energy drink- no alcohol will be consumed in the production of my short film. As the teenagers will be "partying" in some scenes with alcohol present, the scenes following this will be displaying the negative effects of alcohol therefore it is not being portrayed in a negative light whatsoever.

Narrative (edited since filming):

To begin with I wrote up a script for the actors to read from however the acting seemed too staged and not like the natural flowing conversation of stereotypical teenagers. After this did not go how I wanted it to, I decided I would trial not having a set script for the actors. My primary research questionnaire came back with the results that the target audience preferred short films with less narrative so with this in mind, improvisation was the next step. Before filming each scene I briefed them with what I wanted them to be discussing and through this I discovered the narrative worked much better without being planned; it sounded much less staged and it made the speech much more relatable and comfortable where it was natural. If my short film needed to be any longer I would have featured much more speech but I have decided to go unscripted for this one because I like the effect it has on the actors on camera. I believe the plot itself seems much more relatable this way which is what I wanted for the target audience.
