This non-movie basically goes like this:
AW DAMMIT! I don't want to spend time with my step-mother - okay okay I will.
WHAT WAS THAT? Something attacked the dog. What? I. Don't. Know. Well, we gotta shoot it.
WHAT WAS THAT AGAIN? A bloody man shows up. Takes the dad's rifle. Nothing happens.
WHAT DID HE SAY? We're all gonna die. Oh, okay.
WHAT DID YOU SAY? I didn't say anything sheesh get off my case.
WHAT WAS THAT? What was what? There's nothing out there or in here. Dad's drinking again.
WHAT DID YOU DO? Nothing, what's your problem? Don't go outside, we're all gonna die.
WHY ARE WE GONNA DIE? Dunno. Oh. Let's look out the window for <looks at watch> another half hour or so.
DAD DON'T STAY OUTSIDE! He's dead. Well, I told him.
STEPMOM DON'T! She's dead. Didn't like her anyway.
WAIT STRANGER! I'll show you... BLAM! HA! Shot you for nothing!
LET'S GET OUT OF HERE! Bro and sis take car and drive really fast in movie duh style, meaning they promptly crash and flip the car. Bro is dead - sis walks back to the house.
WE'RE ALL GONNA DIE. I am alone now. The end.
Did I miss anything? Ummm, nope, that was it.
