Captain Stronk Cat, a CIA agent, is called by the Brookhaven mayor to investigate a mysterious case where many students are acting weird, walking with their backs broken. The mayor suspects it might be related to a food truck that sells tacos. Captain Stronk Cat, along with his team, including Bobo Bear and Banker, start investigating the taco truck, but it leads to a dead end. They later discover that the school principal is forcing students to drink Coke with a banned sugar called "saucy sugar" as a form of punishment, which is causing the students' backs to break. The principal is eventually caught and exposed.
