Under the Floorboards

Jacob Fischer is unraveling. After the death of his best friend in Vietnam, Jacob is desperately trying to maintain his studies so he won't get drafted as well. But then he starts to see things he can't explain, people who are refusing to stay dead, and there's a mysterious box in his scientist father's basement laboratory. Is Jacob losing his mind in a false reality or is he uncovering something much darker and very, very real?
