Enter the school building and talk to Lisa to begin the next mission. The mission will end when the hover car explodes at the top. Once at the playground, drive the hover car into the tractor beam. (My advice is to not drive too fast and to take as many shortcuts as possible to avoid traffic).
Be careful, if you crash, you will have to go back to the Springfield Nuclear Power Plant to get some more, regardless of where you are. You need to collect some Nuclear Waste from the Springfield Nuclear Power Plant entrance (on the bright side, there's a coin in it for you) and drive it safely to the tractor beam.

Homer stops at the Flanders' House where you have to talk to Ned, persuading him to let you have is First Aid kit. Lisa is more concerned than Homer is (he wants to watch the baseball match) but goes out in search of supplies when Kent Brockman gets eaten by the zombies. The mission begins inside the Simpsons' House where you have to talk to Lisa. Anywhere between these two points cannot be accessed. A large section of the map is cut off which was previously accessible in levels 1 and 4: The ramp down the road from the school is barricaded and a large metal door blocks off the interior of the power plant.
