They head back to the dorm to do a little investigating. The college kids aren’t there, but they find a clue: a receipt that has 10,000 loyal shopper points from Bazo’s Grocery. Suddenly, two gangsters walk in. Devry is one of them and Shawn soon realizes he’s the guy whose Check Cashing place got robbed earlier. Turns out it was the two college kids, whose names we learn are Chris and Dickie, that robbed Devry’s store... but why?
Shawn and Gus are now on a ride-along with McNab. The guys convince McNab to take them to Bazo’s Grocery to investigate a lead they found at Chris and Dickie’s dorm. They lie about their intentions at the grocery store so McNab won’t find out. McNab agrees, and they show up at Bazo’s.
Shawn and Gus sneak into the back where they discover that Bazo is a heavily armed bookie. They confront Bazo, trying to speak on behalf of Chris and Dickie, who apparently owed Bazo tons of money. Bazo says Chris and Dickie paid him off last night. Shawn and Gus figure it out that Chris and Dickie robbed Devry’s check cashing place to pay off Bazo and could now be in serious trouble with Devry.
Shawn and Gus realize they can catch these guys, so they find Nick and recruit him to help and to redeem himself in the eyes of Lassie... for a second try. Nick agrees, grabs the scent dog, Fenway, and they head out. Fenway is able to track down Chris and Dickie’s scent. But Dickie tells them that Devry just kidnapped Chris. They figure out that Devry has Shawn’s walkie talkie -- that is why he is always two steps ahead of them. Dickie suddenly pulls a gun on Shawn and Gus and leaves to go save Chris. The guys have no choice but to come clean to the chief. She in turn extends Nick’s suspension, and reinstates Shawn and Gus as consultants because they were able to track down their suspects before they could. But they are never allowed to wear police blues again.
Shawn and Gus realize Dickie went to Bazo’s to steal the cash back from Bazo to pay Devry off to get Chris back. Shawn and Gus show up at Bazo’s where a gunfight has already broken out between Dickie, Devry’s men and Bazo’s men. Devry starts unloading his gun on Bazo. Then Shawn gets the idea to have them take each other out. He gets on the grocery store intercom and tells the bad guys where each are hiding. Each camp starts to take each other out one by one. It’s working, and all that’s left is Bazo and Devry. Devry shoots Bazo and is now on the hunt for Dickie. Shawn gets the idea to take Nick’s gun, and he looks for Devry. Devry has his gun trained on Shawn and has Chris is in his clutches. Shawn kicks his gun over toward Nick’s direction. Nick picks up the gun, steps in, and miraculously shoots the gun out of Devry’s hands and saves the day. Shawn is saved. Chris is saved. And Devry and Bazo are both caught.
Back at SBPD, Shawn and Gus are congratulated for bringing down the bad guys -- for good this time. Nick is congratulated too. Lassie offers a bit of kindness and tells Nick that the best officers come out of his classes at the academy. Vick informs Nick that his suspension is therefore revoked.
