For my story, I would like a character to be the target of the villains, cause he knows too much. But he blackmails the villains by having evidence on them, put away in safe place, which will only be made public, should he meet some sort of 'accident', if that makes sense. Now since I am writing on a very low budget, I would like to avoid setting it so that the evidence is kept in safe deposit box at a bank. Usually that's how it works, and how the evidence is arranged to be made public, should the owner of the box, dies. However, since a bank is expensive too shoot in, and more expensive, to shoot a robbery scene in, where the vault is broken into, I wanted to change it to a self storage facility, in which the storage unit is robbed. That would be much cheaper to shoot on cause the filmmakers can just rent out a storage unit, go in there at night when no one is around and film a the storage unit being robbed. Only it's not really being robbed, since we the filmmakers are renting the unit, so we are breaking the locks off our own unit, and it's cheap to film that. But after getting feedback from some readers that they said that it doesn't make sense for the character to use a self storage facility, to do a bank's job, and it's just not logical. Is their a way write this blackmail scenario, so that a bank does have to be used at all, and it can still make sense to the reader? Thanks for the input. I really appreciate it.
