Mike is from Queens, NY and he’s super-psyched for the start of his Christmas vacation.
Unfortunately, everything goes south when he finds out that his horrible cousin Mary Lou from Kalamazoo is coming to visit NYC for the holidays. She is rude, disgusting, obnoxious and totally going to ruin Mike’s week off from school.
His only hope is to scare her away by introducing her to the ghosts, ghouls and goblins that lurk at all Manhattan's famous landmarks and tourist attractions.
