It Haunts

Cynthia, a 7 year old girl, lives with her big sister in a huge mansion. Ever since her parents passed away, she has not spoken a single word. But each day her Big sister, Grace, encourages her to atleast speak up a word! But all in vain.
Everything is going smooth and normal, I suppose, until things start getting a little spooky for the Little Cynthia. Unfortunately for her, her big sister doesn't believe in ghosts or anything.
" A Childish thing and Literally dumb thing to believe in it!" , saying this she'd always snub her off.
Eventually, things get so out of control that both sisters try to fight it off all by themselves.
