Ben picks up a summer cold, leaving him at the mercy of both a severely runny nose and Grandpa Max's malodorous Asian remedy. Meanwhile, a villain with power over bugs takes his wrath out on a city when its councilwoman attempts to demolish the dilapidated building he and his bug hordes live in. Ben's cold impedes his efforts to rescue the kidnapped councilwoman by adversely affecting his transformations. Worst of all is the bug maniac's final retaliation - setting the city's nuclear power plant to meltdown and explode.
