Skeletons & Scarecrows

After agreeing to find out why Harbro has not delivered his famous rye whiskey for the upcoming mid-summer festival, Adrok, Bowden, and Chip head out to Harbro's farm and distillery. Upon arriving at the farm, our adventures discover all is not well at the Harbro farm.
No one is tending the farm, animals are wandering. The Harbro family dog leads the adventurers to the main house, where they discover the fate of the Harbro family. Unknown assailants attacked and dragged off the family after what appears to be a hard fought but ultimately losing fight. 
Further searching brings Bowdin, Adrok and Chip to the barn and distillery where a quartet of skeletons rise from the straw and attack.
The skeletons are outmatched by our heroes and quickly flee. The trio pursue the fleeing skeletons intent on putting the unnatural creatures to a final rest only to be ambushed by a living scarecrow.
Do our heroes have what it takes to survive?
What has brought this evil unto the Harbro family?
