A biohazard removal crew go to the site of a multiple murder/suicide to clean up the mess; while there, supernatural stuff starts to happen. When they try to escape from the house, they find all exits barred. Then more spooky stuff happens, none of which makes any sense. After a couple of the crew are killed, those left find some cheesy explanation for the occurrences - A Nordic demon is in the house - and more stuff happens. The only chance for survival is to find some ancient runic stones and destroy them-but the demon is too powerful. Cue end credits, during which some more stuff happens.
A flimsy plot stretched out to just about feature length by loads of random shizz (and some clichéd relationship drama), clumsy direction, and passable effects: Murder House (AKA 11th Hour Cleaning) is generic, forgettable low-budget horror that struggles to hold one's attention, even at a very short run-time of just 73 minutes (with at least six of those being the end credits). The cast do a reasonable job considering the hokeyness of the script, but at the end of the day, this film does nothing that we haven't seen many times before, and it doesn't do it very well.
