a short film about addiction

I have been thinking about a short film about addiction.
The idea that I have so far is to go to the jail near my house (If I can get permission) and ask for volunteers. I want people who admit to being in prison because of their addictions. I will pick people of different ages, gender, and ethnicity. I then want to ask them what outfit they would like to leave prison in. (Kind of like your first day back to school outfit.) Then I want to have them try to get out of a jail cell with the door wide open while being sprayed with a water cannon/fire hose. I would like to use radiohead "just" or maybe DJ shadow for the water fight scene. I thought that if the jail would allow for them to be rewarded for escaping the cell that perhaps it might make their victories or agonies more vivid. Perhaps not. (These are the things I need input on)
I also can't decide if guards should be holding the water cannon or, the other participants, or the shadow people (what many people see during withdrawls, I think they are actual demons).

So you have a person in a prison cell with the door open-(A prison which can be left)
Fighting a deluge of water, being pumeled by the water-(forces of addiction/effects)
Dressed in the clothes they want to leave prison in--(the idea of freedom and what it will look like.)

So if any of you have suggestions, they are welcome. Or if any of you have resources and want to run with the project let me know.
