Friends are out on their bikes, on a run to Sturgis when one, then another race through what seems to be a small fog bank that suddenly appears before them.
But it reaches toward the first biker with an appendage. Time slows to a frame freeze as the second biker through watches his friend lay his bike down.
Three others avoid the fog or whatever it is and witness something unbelievable eerie. How many live to tell the tale?
