I just watched a movie called "Storm Warning" (2007). I found it on a well known internet based dvd rental agency. Three men living alone on an island are visited by a couple who is lost. Turns out the three men are crazy drug dealers. They make the couple slaves. Pretty disturbing stuff, including the butchering of a baby kangaroo. However, around one hour ten minutes into the film, one of the "farmers" rapes the woman. Turns out she inserted a personal defense device which really tore him up. A few minutes later we see him trying to remove it with pliers. The family dog finishes what she starts. Very graphic.
