Dexter Reed, a high school student counting the days until summer break, looks forward to a carefree vacation. However, his plans are derailed when he crashes his mother’s car into the vehicle of his stern teacher, Mr. Wheat. To pay for the damages, Dexter takes a summer job at Good Burger, a run-down but friendly neighborhood fast-food joint. Here, he meets Ed, a slow-witted but cheerful employee who loves working at Good Burger and accidentally causes Dexter to become entangled in more antics than he anticipated. Their friendship begins with reluctance but soon evolves into a comedic partnership based on a shared goal.

Things take a competitive turn when Mondo Burger, a flashy and imposing rival restaurant, sets up shop across the street, threatening to drive Good Burger out of business. Dexter, initially only concerned about earning enough money to pay off the car repair, finds himself invested in saving Good Burger from its ruthless competition. With Ed's secret sauce becoming the only hope to draw customers back to their humble eatery, Dexter and Ed must come up with creative ways to thwart the encroaching corporate threat. As they navigate various mishaps and plot evil plans, the duo discovers the importance of friendship and loyalty in their quest to ensure their quirky little burger joint survives against all odds.
