Dog Bytes (2013)

In a creepy story about poison, eggs and holes, as a step daughter acts out a revenge fantasy. The problem is, revenge fantasy plots can have unexpected outcomes, they can even fail ...miserably... and create a whole world of problems for the gals on the business end of the fantasy. And, of course, there are dogs-they turn up, and the next thing you know everybody's in a single-wide (not even a double-wide) looking at a pile of bones, but not the right bones.
