Ace Savvy and One-Eyed Jack are in the Fortress of Solitaire where they are finally solving a case. Before Ace reveals who did it, it goes back to Lincoln and Clyde who celebrate the fifth case their heroes have solved, only to be interrupted by Leni who is crying. When Lincoln and Clyde ask what happened, Leni reveals that during her job at Reiningers, her boss, Ms. Carmichael, called her to tell her something important, which Leni initially mistook as an invitation for a scavenger hunt. In reality, she is going to fire her. It turns out that Ms. Carmichael believes that Leni stole several scarves. After hearing her plight, Lincoln and Clyde decide to take the case.
At the mall, Clyde and Lincoln start their investigation, only to be interrupted by Carmichael's son who wants to play with them as his mom is too busy to pay attention to him. While watching Gabby attempting to buy some scarves, Lincoln and Clyde assume instantly that she is the culprit, only to discover that she is actually attempting to buy them with her mom's credit card. After bumping into a stand of training bras which frustrates Fiona, Lincoln and Clyde see Scoots shoplifting some scarves. In an attempt to stop her, they make a tripwire made of clothes hangers only to fail (and also find out that Scoots was actually in a hurry to buy the scarves because she's late for a party), making both Lincoln and Clyde crash into a stand of fragrance which causes Fiona to be angry again. While thinking of a new plan, they discover Fiona running away holding a duffel bag which has a blue cloth. Assuming they have finally found the culprit, they call Ms. Carmichael, while dismissing her son again, at the parking lot, they make Fiona reveal that she actually bought a dress from the competitor's store.
Lincoln and Clyde disappointed in their failure, lament that they don't deserve wearing their costumes, only for Leni to state that a cape can also be a scarf, which causes Lincoln and Clyde to discover the real culprit. Back at the mall, they convince Ms. Carmichael to give them another chance. They ask her son if he wants to play superheroes with them, which causes him to lead them to his hideout, revealing that he was the one who took the scarves as he mistook them for capes. Realizing her mistake, she thanks Lincoln and Clyde.
Back at her job, Leni encounters Ms. Carmichael who wants to apologize for firing Leni and asks her how can she make it up to her. Lincoln and Clyde later bump into Leni, who thanks the duo and tells them they got another case. While Lincoln and Clyde are celebrating their success, they once again bump into a stand that has sunglasses, angering Fiona once again.
