It's kinda like the punk rock Hardy Boys versus monsters...

It’s the night before the SAT test. The forces of darkness are stirring.

Twin brothers, Bing and Ron Slaughter, know they’ve got to cram like their lives depend on it because their college plans sure do. If they don’t ace the test, they’ll be doomed to spend the rest of their days flipping burgers at the McDonald’s their parents run. That’s why they hatch a plan to meet up with the members of their punk band, the Ephits, spend the night studying at their secluded cabin in the woods, and maybe squeeze in a little jamming. What could go wrong with a brilliant plan like that?  

Ancient evil. That’s what.

As a cataclysmic lightning storm rolls in, Bing, Ron and the rest of the Ephits find themselves tangled in a sinister plot to summon a demon. Yes, demons are real. To survive the night, the band must find a malevolent artifact, battle bloodthirsty monsters and stand against the most dangerous and powerful foe humanity has ever faced…the Golfer’s Association.
