Psych

An 11 year-old kid hires Shawn and Gus to retrieve his stolen Darth Vader action figure collectible from the British Ambassador's son's room at their temporary residence in Santa Barbara. Shawn successfully sneaks into the Ambassador's residence during a lavish party the Ambassador is hosting in honor of successfully exonerating Colin, a British student, of murdering his girlfriend Sarah. Shawn successfully retains the Darth Vader, but in the process he comes across the body of a dead woman. Before he is able to investigate, he is forced to escape, as his presence is discovered by guards. Shawn quickly escapes, but not before he is spotted and chased. Shawn narrowly escapes, but now he and Gus have a murder to solve.

Shawn, Gus, Lassiter, and Woody wake up in the Psych office with no recollection of what happened the night before. When a body shows up dead, the quartet conduct a discreet investigation in order to exonerate themselves and find the real killer.

Lassiter's new relationship with a mysterious and beautiful woman is placed in jeopardy when Shawn and Gus are convinced she is a murderer -- the same murderer responsible for the blood-drained body the SBPD is investigating.

A local drug syndicate known as the Caminos falls under attack by a masked vigilante called The Mantis, and Lassiter is soured by this since The Mantis has already made more progress than the police. Shawn is also put off, due to Juliet expressing an admiration for The Mantis' efforts. Shawn and Gus believe that a new cop is the vigilante, but as they put the pieces together, they start to believe that the Mantis' efforts may not be altruistic.

When the hitting coach of the local minor league baseball team suddenly dies with amphetamines in his system, the team's manager believes it to be foul play, so he hires Shawn and Gus to go undercover as the new coach and mascot in order to investigate.

A billionaire that Lassiter investigated for murder avoids a jail sentence by means of an insanity defense. After he is sent to a mental hospital, Shawn and Gus go undercover as a patient and orderly to prove that the man is sane, but Shawn asks the question that Lassiter didn't even consider - what if the man is actually crazy?

As Juliet's birthday approaches, Shawn takes it upon himself – due to his own daddy issues – to reunite her with her estranged father Frank O'Hara, without taking the time to learn that he's a con-man. Not wanting Juliet to be resentful, Shawn hires Frank to assist them in a case involving a safe cracker who was broken out of jail.

Shawn and Gus are at the SBPD waiting to pick up their check when they spot an attractive, ethereal woman named Nicole, telling the police that she witnessed a murder in an ally on a busy street at the height of lunch hour. Given the circumstances, Lassiter and Juliet are unsure whether or not she is telling the truth. Her story sounds unbelievable even to Shawn, but Gus is really attracted to Nicole and wants to further investigate.

A businessman named Jerry Kincaid is conned and robbed by a couple named Barbie and Clive. After Barbie and Clive flee the scene of the robbery, they arrive at a swanky resort hotel where we learn that Juliet and Shawn have just checked into — with the help of Shawn stealing Gus's credit card, naturally. Juliet and Shawn are there for a romantic weekend getaway — one they have promised will be completely devoid of police work and instead, filled with the opportunity to take their relationship to the next level.

As Gus confronts Shawn over the diamond ring he just discovered, a valuable shipment of artifacts is stolen from a museum, so Shawn calls in Pierre Despereaux to help them catch the thief who stole the shipment. It turns out to be an old dagger that she was really after. As usual, nothing is what it seems when Despereaux is involved, and they discover that the dagger is the key to a much bigger mystery.

After Lassiter moves in to a new condo when the previous tenant was found dead, he hires Shawn and Gus to investigate the strange events that begin going on.

A contestant on a reality TV show in the style of The Bachelorette lands in a coma after a car crash. Immediately Shawn deduces it was no accident, so he and Gus go undercover as two new contestants. Shawn thinks that the culprit is after the show's bachelorette until his main suspect is nearly killed, and he starts to question the culprit's motive.

When the founder of Right Now, Santa Barbara's oldest at-risk youth program, is shot and almost killed, Shawn, Gus, and the available members of Gus's accapella group from college investigate to find the culprit.

A mortician, Grace Larsen, whom we learn was a classmate and former lover of Woody's, has informed the SBPD that she believes Woody made a mistake on a recent autopsy. The file on the deceased, Bob White, tells us that Bob's ear was severed cleanly with an instrument and not, as was originally reported by Woody, that it was slashed by a tire in the bus accident which killed him. So as a result of this news, Bob's death could have been murder and not an accident. Woody's position as medical examiner is in jeopardy, and Chief Vick orders Shawn and Gus to help re-investigate Bob's death and try to clear Woody's name.

A local news report is shown profiling a Santa Barbara man, Thane, who was just released from prison after his lawyer from The Innocence Project discovered he was wrongfully convicted of robbing a restaurant he worked at. Thane is very outspoken about this injustice and as a result, is very weary of police and the legal system as a whole. Instead of going to the SBPD, Thane asks Shawn and Gus to help get his restitution settlement. In order to obtain it, the real culprit of the crime that Thane was wrongfully committed of, needs to be found, tried and convicted, or Thane gets no restitution money. Shawn and Gus agree to help, as Thane convinces them that this case should be part of their civic duty to humanity. Shawn and Gus are instantly spellbound by Thane's emphatic "justice shall be served" attitude, and agree to help.

After over 20 years of searching, the body of Veronica Towne has been found, and Shawn, Gus, and Henry reopen the case and revisit all the old suspects, including the son of a millionaire who was dating her at the time she went missing.
