The first night with his mom gone, it is stormy and Rusty hears noises in the attic. He goes to investigate, but just finds Richard soaking wet and Richard tells him to stay out of there. Of course, he doesn't and he finds the body of the missing mailman, a friend of his named Chuck (Casey Myers). I was a bit shocked that the stepson finds a body this early in the movie, but at the time, he just thinks that his dad is a murderer. He calls the cops, but given his reputation of being a joker and the fact that they don't find anything in the attic, they just tell Rusty to stop making up stories. No one believes him, not even his friends, so when he gets a note on his locker to meet up at 8 about his stepdad, he goes. The man who shows up is the janitor at their school, Gert (John Redmond), so they just laugh at him, at least until Chuck shows up with newly acquired fangs. When Gert saves them, he then explains to the boys what is going on, who Richard is, how they can defeat him, and what happens if they don't! From here, their lives will never be the same again.
Rusty is apparently a member of the family bloodline that possesses a weapon that can stop the vampires, if they can just figure out what it is. Along with Gert's help, Rusty and Travis have to figure out what the weapon is and how to use it before Richard can find it and stop them. Given that things don't always go as planned, especially when in the hands of teenagers, is the entire world doomed?
There is a Blooper reel in the Special Features that is funny, as you would expect from a comedic horror movie. It's pretty much the only extra feature other than commentary, trailers, and previews. My Stepdad's A Freakin' Vampire is a decent vampire movie in the vein of The Lost Boys. It is more comedy than horror, though. The special effects are a bit obvious at times, but the story is amusing so you don't notice it too often. If you're looking for a comedic horror movie, you might check out My Stepdad's A Freakin' Vampire.
