Ralph Filmore is just your average, every day, 12 year old Paranormal Investigator. He hunts down and challenges all things strange and bizarre on a daily basis, despite being the shortest kid in 7th grade, getting picked on by bullies, and still having to be in bed by 9 PM. Ralph's serious obsession for paranormal phenomena gets him into heaps of trouble, but with his best friend/partner in slime, Booker, his trusty robotic supercomputer, Z and his ghostly canine companion, Specter, Ralph protects the people of Earth from extraterrestrial and supernatural threats.
