I was flipping through the free On Demand movies and came across Toolbox Murders HD and thought I would give it a try - after all it was free (it was directed by the man who did Texas Chainsaw Massacre so I wasn't sure about this one!) but I really was surprised that I was not disappointed.
Steven and his wife Tess move into an old apartment building; he is in Medical School and is working in the ER as an intern, so he's not home much. But his wife hears unexplained screams from the neighbors through the thin walls. The landlord is not much help as he attributes all the noise to "the charm of the building" - Tess calls the police 2 times because of the horror she hears but nothing is to be found and the police very nicely think she's overreacting.
In this movie you have a boy next door who spies on Tess' neighbor with his computer, an off-the-wall girl right next door with an abusive boyfriend, an old man who has lived in the building for over 40 years, a handyman who is freaky looking, and some more odd characters.
Anyway, the neighbors are getting killed with power tools; a power drill through the head, a nail gun in the throat, and much more so it could be a little gruesome but without too much to wanna make you puke. Now it's up to Tess to find out what's going on when her neighbors turn up missing and no one believes her. She also realizes that each floor has no apartment #4, which is strange indeed.
If you like suspense, this movie has it; it was not too ridiculous as some thrillers can be, and the grossness I would rate at about a 3; not too much but enough to make you want to leave your toolbox the hell alone.
