First off, I hate when you HAVE to read the synopsis prior to watching the trailer. If the editors can’t find enough good footage to make a decent trailer it does not bode too well for the film in my opinion.
But, because we are nice check out the deets for Slender Man:
In a small town in Massachusetts, four high school girls perform a ritual in an attempt to debunk the lore of SLENDER MAN. When one of the girls goes mysteriously missing, they begin to suspect that she is, in fact, HIS latest victim.
Slender Man is in theaters May 18, 2018.
