A decade has passed in the small town where the original Sandlot gang banded together during the summer of ’62 to play baseball and battle the Beast. Now, back at the dugout, nine new kids descend on the diamond only to discover that a descendant of the Beast lives in Mr. Mertle’s backyard – a monster of mythical proportions known as 'The Great Fear'.

Four interwoven stories that occur on Halloween: an everyday high school principal has a secret life as a serial killer; a college virgin might have just met the one guy for her; a group of teenagers pull a mean prank, and a bitter old recluse receives an uninvited guest.
