The episode starts with Miss Finster initiating "Operation Field Trip." Before leaving for MISOOE (Museum of Industry, Science, Oceanography, Oddities, and Energy) Bertha is upset about her beloved bus Old Smokey being reduced to recycled metal after this field trip.
As the students leave for MISOOE, Miss Grotke leads them in singing "This Old Man" ad nauseam until Old Smokey breaks down, leaving those inside stranded by an abandoned farm.
While Bertha is moping about her situation, and Miss Grotke is trying to calm her down, the kids decide to make Bertha happy by fixing her bus (and then some).

- "Take'm to MISOOE" is a reference to the 1948 western film, Red River.
