What is the title of the full movie/DVD? Which studio is it from?

So, I stumbled upon this movie. Here is everything I know: The credits claim that her name is Missy and the guy is named Mark Davis. Furthermore, it is directed by a Jim Gunn. And it seems like the clip above is complete. Although, it also seems like this is a scene of a longer movie. So I am looking for the title of the full movie/DVD of this clip, as well as a studio. Anybody got any idea? Maybe even an IAFD link?

Optional: The clip in higher quality.
