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. However, the plot thickens when Shawn realizes the guy is innocent.
The Santa Barbara police department is on high alert. Dwayne Tancana, arrested for the home invasion robbery turned murder of Isabella Cole, escaped custody on his way to arraignment by head-butting Juliet as they rounded a corner. Now it's a full on manhunt, and to Lassiter's chagrin, the victim's husband has hired bounty hunter Byrd Tatums to ensure his wife's killer is found and brought to justice. Juliet is eager to get out there and correct her mistake, but unfortunately Lassiter has to bench her at the office, ensuring her he'll use every resource to find Tancana. Juliet takes him literally and calls in Shawn and Gus. Lassiter tells them they are only to locate Tancana and call them in. He's too dangerous for them to bring in themselves, he explains, and shows them pictures of Isabella's strangled corpse as proof.
Before they agree to take the case, Shawn asks Cole if they are eligible for his bounty money, and while he's at it, envies his ginger scented hair gel, Kangaroo Paste, which you can only get from Australia. Byrd tells them to stay out of his way. This is his last job, which will give him enough to retire on. Now Shawn and Gus have extra incentive to bring in Tancana first, not only to help Juliet, but also to beat Byrd, and while everyone else is checking routes out of town, Shawn knows Tancana will be laying low to avoid detection. They check with Juliet, who is watching a video of the escape, to see if Tancana has any relatives in town. On the screen, Shawn notices Tancana's wearing a medic alert bracelet and asks if he as a heart condition. Juliet confirms this and tells them that he has a cousin who's a short order cook at Marvin's diner, but that was the first place they checked.
Regardless, they head to Marvin's, a greasy spoon, to talk to the cousin who denies having seen Tancana. But Shawn notices a heart healthy meal on the grill, next to all the melts and burgers, and deduces Tancana is actually there now. Just as they are about to grab him, Byrd show up and handcuffs him for himself. Tancana doesn't come quietly, head-butting Byrd and making a run for it. As Shawn and Gus jump in the Echo to pursue, they find Tancana, already in the back of the car, having the same idea for escape. But on their way to take him back into custody, Tancana asks them to make a stop first and gives them directions. He needs to find his partner in the robbery, Delbecchio, to prove he didn't murder Isabella Cole. They didn't make much from the robbery but Delbecchio kept talking about a big score. Shawn and Gus refuse and take him back to the station, but before the cops can come out and take custody, Tancana has escaped, using his handcuffs to lock Shawn and Gus to the car.
