New cadets arrive at the Metropolitan Police Academy, now under the leadership of Commandant Hefilfinger. The cadets must rescue their hard-nosed instructor Sgt. Ledbetter, after he is kidnapped by a biker gang.
Hefilfinger organises a Cadet of the Year competition to increase the number of Academy enlistments, but Ledbetter does his best to keep Casey from winning. Due to budget cuts, Commissioner Hurst is named the new Commandant.
Ledbetter and the cadets embark on a ski trip for winter break. Alice & Annie have the hots for a handsome concierge. The Tackleberrys try befriending Lester. Casey meets the love of his life, but has trouble being accepted by her father.
