This is absolutely the worst movie I have ever seen. I was ready for a sharp heist where, you, as the viewer, had to be aware of every move to figure the outcome of the movie, but this movie did not deliver that. This is pretty straightforward; everyone involved with armored security trucks is stealing the money.
It is a low budget film with cheap effects. The dialogue is practically nonexistent. The first speaking parts are at the armored truck place of business with a dialogue of quick quips back and forth among many employees which are meant to be dry, witty, and cutting banter. They seem like memorized movie script lines that are quickly spat out, then here comes the next one.
Acting? there was none, I fell asleep during some scene with Johnny Cash music blasting really loudly. I woke up (just a quick nap) and made it through to the end of the movie, waiting for some thrilling ending. There was none, just a confused subplot. By the way, what happened to the first team of robbers? Are they still out there continuing their armored truck heists?
Anyway, my advice is to stay far away from armored trucks and save your money on this film.
