Grandpa (2013)

Milo is a troubled kid. He's having night terrors, little accidents, and his only friend has lost an eye. Luke, his father, is blind to Milo's problems. He's overworked, underpaid, and up to his eyes in debt. They live in Grandpa's old house; not so much an inheritance than a millstone round their necks. But something is changing. And Grandpa keeps watch.
