Shawn and Gus return to Vancouver to visit their old nemesis Despereaux in prison at the felon's request, who then uses them to escape and pull one last job before he is extradited to the United States. Only while he is out, he is framed for the murder of a Crown Attorney and now asks the guys for help clearing his name of this most recent – and frankly unseemly – charge.
Shawn and Gus receive an invitation from Desperaux to visit him in British Columbia, but there's a catch: Desperaux is still in prison. But after much convincing, Gus agrees to go with Shawn on the free trip. Fresh off sharing a kiss with Juliet, Shawn is faced with telling her his feelings before she leaves for the Amalfi Coast with her boyfriend Declan, and before he and Gus leave for British Columbia. However, Shawn misses his chance after McNab tells him that Juliet asked him with help with her passport, meaning she already left for Italy.
At the British Columbian prison, the boys meet up with Desperaux. After they leave, Desperaux suddenly appears in the back seat of their car. He explains he needed a visitor to make his escape work. Desperaux ends up tricking them and steals their car.
Shortly after, Shawn and Gus head to the RCMP headquarters to tip off the police about Desperaux escaping form prison. Mackintosh says that they recently found their best detective dead, and that things at the RCMP are tad nuts. But Mackintosh calls the prison anyway, and the prison guard tells them that every prisoner has been accounted for. But almost immediately after, they get a call about an art theft at the Crown Prosecutor's house. Shawn and Gus immediately think it's Desperaux that did it. But things get extra hairy when they find out that the Crown Prosecutor has been killed.
The guys head back to prison and see that Desperaux has in fact broken back into prison, sight unseen. Desperaux admits to the art theft, saying that the perfect alibi was to be in prison. But Shawn stops Desperaux when he tells him that they found a dead body in the same house he robbed. But Desperaux denies killing anyone; he thinks he's been set up. Shawn and Gus do not believe him and leave. Shawn and Gus are surprised to see Lassiter in the RCMP office. He is there to extradite Desperaux. Much to Shawn's surprise, Juliet is there too. She didn't go to the Amalfi Coast with Declan. Shawn tells her he needs to talk to her, but can't do it now.
