Box: Metaphor

In a dystopian future, crime has skyrocketed. Criminals are sentenced to die or imprisoned in a metal box. A woman has been sentenced to 7 years although she claims to be innocent. Each box is given supplies through the mercy of citizens although mostly, it shows the cruelty of humanity.

This is an Australian indie. Initially, it reminds me of Cube although we are not moving outside of this box. We're kind of stuck here. That's the main drawback. There are other movies like this. I don't mind an out-of-the-box concept, but they need to get out of this box. My suggestion is a flashback to show how she was convicted. This is an undercooked idea movie. It just needs more time in the oven.
