Pumpkin Halloween

Keith absolutely loves Halloween.
Each Halloween night, he will join his friends to go trick or treating.
Then, one misty Halloween night, Keith and his friends accidentally stumbled into a street.
A street linked to the unsolved cases of missing children...
Then something paranormal happened...
How come Keith can see his beloved dead Grandma? What will happen once you drink the Water of Oblivion? Who have been abducting the missing children?
It seems that Keith had stumbled into a place he does not suppose to go.
Can Keith escape this place before it is too late?
Just another urban legend, right?
