Plot
After enduring his first day of junior high school, Kevin is befriended on the bus ride home by Tracy Donnelly who offers him a sympathetic ear, saying she knows what's it's like to be new. She drops her pencil and Kevin picks it up, only to find that the girl has vanished. Her name is inscribed on the pencil.
While doing his homework Kevin passes his mother the pencil, and she states that the house is full of them - the Donnelly family used to live in the same house, before moving away after their daughter Tracy was killed in a bus accident.
Kevin realizes that Tracy is a ghost and anticipates meeting her again on the bus. Tracy is flirtatious with him, and before disappearing, gives him some homework - a bus safety manual to read. At hom,e Kevin ignores the leaflet, so Tracy haunts him; moving his weights, changing his radio stations, and fluttering the manual until he agrees to read it, learning emergency procedures as he does so.
