A report on TV tells us that a regional drug trafficking gang, The Camino Drug Syndicate, has been successfully moving thousands of kilos of product through the streets of Santa Barbara.
We come up on Shawn and Gus in hot pursuit of four criminals. Gus pulls a hammy and forces them to stop. When Gus finally recovers, they approach the criminals to see they have already been taken . Shawn approaches the now tied-up criminals and sees that the shadowy figure left a note in one of their mouths that simply says: "The Mantis". Later, SBPD arrives to get some answers. Just when they think they have no solid leads on who accosted the bad guys, they all look up and see a man, wearing a neoprene bodysuit, run and leap off the rear of the building. From this, Shawn and Gus are convinced this was the work of a real life super hero.
Back at SBPD, a reporter, REGINALD PARKER, from the Santa Barbara Sentinel is questioning Lassiter and Vick about the vigilante/super hero guy called The Mantis that took down the drug ring criminals. Lassiter is soured by this line of questioning because this vigilante has made more progress in taking down the drug ring than SBPD has.
Later, Juliet presents information regarding The Mantis's recent criminal takedowns. Shawn is visibly jealous of The Mantis, as Juliet appears to be impressed by his brave efforts.
Desperate to find out who The Mantis is, Shawn Shawnvisions clues in the SBPD that lead him to believe Camino's drug shipments are clocked by certain phases of the moon. Shawn then "psychically" relays this information to Juliet and Lassiter. They are willing to entertain Shawn's vision and decide to obtain a warrant to check out the docks.
They arrive at the docks and are shocked to see the bad guys have already been taken out by The Mantis. From this, Shawn concludes that there is no way that The Mantis could have known that the bad guys would be at this location, on the same night and time as Shawn "divined", unless The Mantis was someone on the inside... someone who works for the SBPD.
Back at the SBPD, Shawn and Gus seek out possible options for who could be the mantis. They predict that he may be the new officer just hired on the SBPD — a man who is particularly fit.
Shawn SV's a clue from a text on Juliet's phone regarding the Camino's next drug shipment. From this, Shawn is able to arrive on the scene before the SBPD does. However, this scenario backfires for Shawn when they rip the mask off the supposed real Mantis and discover that it's Shawn... in the Mantis's mask and outfit. Shawn tells the truth about what happened: The Mantis knocked Shawn out, dressed in his clothes, and fled.
Shawn shares his "inside job" theory to the group. Lassiter tells Shawn to prove it, and Shawn runs up to Officer Reynolds telling him that he should reveal his true identity — that he is The Mantis. However, after Shawn discovers that Reynold's has no marks on his body that would indictate he was in a fight, this theory is quickly dismissed.
