Shawn and Gus help the SBPD solve a case, but are soon reprimanded for their efforts because they did not follow police procedure. As a result, Chief Vick arranges for them to take a three-week crash course at the Police Academy, but in true Shawn and Gus fashion, they end up resorting back to their rogue investigation styles regardless.
The SBPD are on a stakeout watching a drug deal play out on their monitors. They are about to take down a criminal they’ve had their eye on for over four months. Then suddenly, through the monitor, the SBPD sees Gus walk in pushing a room service cart. Gus starts to distract the drug dealers. Shawn then jumps out of the room service cart and starts to snoop around. He finds a bag of prescription drugs, but gets caught almost right away. With guns pointed to his head, Shawn asks the drug dealers if they are selling these drugs out of this hotel room. The drug dealers say yes, thus giving Lassiter and the SBPD the confession they needed to take the drug dealers down. But Shawn and Gus are still in danger. Guns start to go off, but thankfully no one is hurt.
The next day, Shawn and Gus think they are being called into the station to be congratulated for ”catching the bad guys.” However, Vick is quick to change their tune when she instead reprimands them for nearly botching the entire stakeout. Vick tells them that they could have been killed because they have zero police training and that they possess an overall lack of respect for police procedure, and therefore tells them that in order to come back to the SBPD as consultants, they need to participate in a three week crash course at the Police Academy. Shawn and Gus are excited by this prospect, as they only see the fun that will ensue, and not the actual hard work part.
Later, the guys show up at the Police Academy dressed in sweats that are exact replicas from the Police Academy movies. The instructor on duty, Officer Nick Conforth, isn’t amused. He gets straight to business. Suddenly Lassiter shows up to make sure Shawn and Gus showed up. Lassie immediately recognizes Nick as one of his former classmates in the Academy. It turns out they are old rivals and Lassiter rubs it in Nick’s face that he’s now head detective and Nick’s just a lowly teacher.
Shawn and Gus start their training and soon prove that they are not police material. Nick is embarrassed for Shawn and Gus. He suggests that they try their luck out in the field. Shawn and Gus are issued official police batons, radios and equipment. They have a little fun and pull over Lassiter. Lassiter is naturally annoyed. He then gets a call about a robbery going on at a Longsdale Check Cashing place. Lassie leaves. Shawn and Gus convince Nick to take them to the crime scene by telling him this could be his chance to redeem himself in the eyes of Lassiter. But once Nick gets on the scene he cowers and chickens out and we learn why Nick decided to lead his life as a teacher instead of a field officer.
Shawn and Gus follow the perp into a dorm building at a college. Shawn and Gus go investigate and find nothing but some hungover college kids. After finding nothing, Lassiter catches them at the crime scene. Nick gets reprimanded by the chief for bringing Shawn and Gus to an active crime scene. She suspends him. Shawn realizes his police radio is gone.
Juliet is the substitute teacher at the academy since Nick has been suspended. Shawn is loving this. He plays with Juliet and tries to discuss a current case in front of the class. After class, Juliet reveals that it was her idea to send Shawn and Gus to the academy so they don’t get killed. Suddenly, Juliet gets a call from Lassie to head to a crime scene. Juliet takes Shawn and Gus with her, but once they arrive on scene, Juliet locks them in the car to keep an eye on them. Juliet’s lead turns out to be a dead end, so Shawn and Gus take matters into their own hands and start to investigate a name they found earlier at the dorm: David Arnold. But they soon find out that David Arnold is a fake name and a mislead planted by someone else. Shawn and Gus realize that the fake name was created by the same hungover guys they ran into at the college dorm earlier that day.
