In 1988, the Wyrick family moves into a new home, which was mysteriously abandoned by the previous owners. Shortly afterward, their four-year-old daughter Heidi begins spending time with an imaginary friend, a kindly old man named Mr. Gordy. Several months later, Heidi is frightened by the appearance of a man at the front door.
There is a ghost that appears with some minor blood on it, and some scratches that also have minor blood. However, there isn't much and nothing excessive.
The movie states that the dog runs away. No mention of it dying.
