A hundred or so years later, a widowed mother of two young girls moves into the family home left to them by the deceased father/husband.
Of course the house is a dilapidated, rat-strewn wreck of a house, but Mom wants to fix it up, clean it up, sell it fast, and move on.
Meanwhile, older daughter, Sarah, meets up with some peers and is told about the ‘Zombie Miner Children’ legend of the surrounding forest, and younger daughter, Emma, has a new ‘imaginary friend,’ Mary, who just happens to 'live' in the woods.
Well, the whole thing plays out just like a decent ghost story should - the deceased rising at night to wreak revenge on the descendants of those that cost them their lives. Yeah, that old chestnut. However, that is both the good and the bad of it: it is more ghost story than zombie flick.
I mean, the minor-miners ARE dead, and apparently eat the flesh of their victims, but they only come out at night, they kill with pickaxes and shovels, they work together as a team, no transmission of Zombism, or any other of the ‘Rules of Romero apply, (aside from the eating of the flesh.)
YouTube has both the trailer, here: WICKED LITTLE THINGS
Or, the whole film (with commercials,) under the name ZOMBIES
Also, as of this wring, it is included with Amazon Prime.
