Elly always gets stuck with entertaining her relatives while their parents talk to her mom. Blah, blah, blah. It goes on for hours. But this time, she worked and worked to make a special surprise for her visiting cousins...a haunted house in the basement! With a super-duper, extra-gross surprise in the spooky cellar.

It should be the most fun that they've had in forever...until things start to go mysteriously wrong...
