It’s four a.m. and an alarm is going off at the Santa Barbara History Museum. Lassiter and Juliet rush in to find that the mummy from the exhibit that opened yesterday is missing along with Hastings, the night watchman, who it turns out has a criminal record. That, combined with the fact that the mummy, along with everything else in the museum, is of so little monetary value that the board of directors keeps postponing the overhaul of the security system, leads Lassiter to conclude this case isn’t worth his time. He tells Juliet to put out an ABP on Hastings’ car and goes to leave but Sophie, the assistant curator, insists there’s more going on. The alarm was triggered from the inside of the museum and although the security isn’t top notch, nowhere on any of the footage does the culprit or mummy appear. She thinks there’s something potentially supernatural going on and she wants the paleosleuth who discovered Zippy the Dinosaur on the case. For once, Lassiter is happy to oblige.

"It’s Gus’ birthday and Shawn gets him the ultimate present. They are both on the VIP list for the fall launch party for Ciao clothing as the modeling team “Black and Tan.” Once in, Gus is excited to see his favorite unknown model, Berlinda Desidovicz, and as he goes over to talk to her, Shawn notices one of Ciao’s owners, Ciaobella, berate her assistant and throw a green shake onto the ground. Just then, the other owner, Ciaobella’s husband Gregor Uwe-Steeb, gets up to give a speech. He starts by saying he did all the designs for the new line, then as he reaches down to adjust the mic stand, he’s electrocuted to death."

Henry is sick, Shawn tells Gus. He called to cancel their weekend camping trip in the mountains and Shawn couldn't be more thrilled, until he catches his dad driving through town, the picture of health. Now Shawn has to know why he was ditched, and he and Gus follow Henry to the Monarch Lodge, where they discover Henry is a member. After Shawn perfectly repeats the secret handshake, they enter the lodge to find Henry in a room full of robed lodge members, surrounding a dead body on the floor. The brothers have called Henry in for help, but he insists he's retired both from the force and the lodge and calls the police.

The police have called Shawn and Gus down to the television studio. There has been a murder on the set of the telenovela “Explosion Gigantesca de Romance,” Gus’ favorite soap opera. But when they get to the set, Lassiter says Juliet jumped the gun calling them and the case is open and shut, in fact the whole thing was caught on tape. One of the actors, Jorge Gama-Lobo stabbed the victim during one of the scenes. But Jorge insists someone switched the prop knife for a real one without his knowledge.

Shawn and Gus have run into a problem on their latest case. They are investigating the disappearance of Oswald Chester in a place that is impossible to sneak into: Glorious Pines, the most exclusive retirement community in Santa Barbara. They convince Henry to go undercover as Talmadge McGulager, who has actually gotten in off the wait list.

Shawn and Gus are being followed by the worst P.I. ever. Shawn's actually taken pictures of himself being surveilled over the last few days. Finally they confront their stalker, who lights a cigarette and confesses that he was hired by Gus' wife. Gus admits to a shocked Shawn that he met Mira Gaffney when he was in Mexico on Spring Break in 1997. She was crazy and could get him to do things no one else could, like skydiving and getting married on a drunken binge. Shawn insists on coming with Gus to meet her and Gus agrees, making Shawn promise not to let him get sucked back into Hurricane Mira again.

When an accused murderer goes on the lam, Shawn and Gus play bounty hunter, racing "Midnight Run" style to bring him in before the cops and a real bounty hunter get him first.

A highly accomplished burglary ring is hitting Santa Barbara homes, all in the middle of the day, leaving no trace of how they gained access. Shawn and Gus want on the case, but Interim Chief Vick has an even more important job for them – she needs them to find her a new nanny. A task they readily accept as a way into the burglary case.

A group of genius teenagers from a school for gifted students claims one of their teachers is a murderer. After striking out with the police, their last hope is Shawn and Gus, who go undercover and soon discover the kids' imaginations might not be so wild after all.
