The opening credits scream "major indie film." Trevor and Rob sell privacy fences. As a hobby they buy estates and sell the junk on E-Bay. They recently moved into a home owned by Bill Zill who had passed away. The man didn't leave much behind, but left stuff that was coded and cryptic. Rob invites his fiancee to come stay with them, an irritating girl named Amber/Brit who was once engaged to Trevor (guess how that works out). Amber talks like people type on the Internet, with phrases like, BFD and BRB. Likewise her and Trevor like to have conversations with their mouth full of food, another bit of annoying indie realism.
It turns out Bill Zill had a love for a web site called "4 Boxes." The 4 boxes are 4 rooms in a house which has cameras. A girl used to run the site, but then left. The house was taken over by a guy who wears a gas mask and is apparently a terrorist making bombs to send to the US. Trevor is trying to figure out who they are, where they are, and if it is real.
The movie ends with a twist, then another twist, and then one stupid ending. I think they should have let the movie go with just the first twist instead of attempting to get cute. Sex, brief nudity, f-bomb. If you really really love low budget indies, then try this one out.
