The city's police force is in desperate need of recruits. Undeterred by the quality of candidates, the mayor enacts a policy that removes all restrictions barring applicants from joining the police academy. This open-door policy leads to a surge of misfits and eccentrics enrolling, much to the chagrin of the stern Lieutenant Harris, who is determined to force them out through rigorous training and harsh discipline. Among the new cadets are a charming trickster with a disregard for authority, a soft-spoken giant with impressive strength, a sound effects wizard, and a wealthy socialite seeking adventure.

Tasked with the challenge of surviving the grueling six-week training program, the diverse group of recruits must overcome their inadequacies and personal conflicts. Despite Harris's relentless attempts to expel them, the cadets forge a bond and begin to show unexpected potential. Their camaraderie is tested as they face humorous obstacles and the demands of their training. Meanwhile, within the chaos, a romance blossoms between the charismatic leader of the group and a fellow cadet who harbors her own aspirations within the law enforcement world.
