The Smith family isn't your typical American family.They are members of a small group of paranormal investigators known as "the Paranormal Society of America." When the Smiths have their first child; their son, William, they are forced to choose between leaving him with relatives and taking him with them on investigations.At first, the family matriarch, Erica, emphatically insists on leaving William with relatives, but one day they can't get anyone to take in their son so they are left with no choice but to bring him with them and that's when they truly become "A Pretty Paranormal Family"
