Lucky for Tom his grandma's best friend just happens to be the world's foremost ghosthunter. Under her expert tutelage, Tom learns the tools of the trade—which just happen to include buckets of graveyard dirt—and soon finds he has to face down not just the Averagely Spooky Ghost (ASG) in his basement but the Incredibly Revolting Ghost (IRG) in town. All while keeping the nettlesome Lola off his trail....
