In a flashback, Jimmy and Marco break into the McGill family's abandoned store in Cicero, Illinois. Jimmy retrieves an old metal Band-Aid box from the ceiling tiles, from which he retrieves his childhood coin collection. He finds an Indian-head penny that he hopes to use in a con game. Jimmy explains that he hid his collection after his father tried to give back a rare George Washington half dollar. Marco expresses genuine remorse for Jimmy's parents losing their store though Jimmy doesn't and he goes on to say that his family were better off not owning the store, saying that his father was only popular because he was too generous with money and implies it was solely his fault for its eventual closure (completely ignoring his own role in its demise). As he and Marco leave, Jimmy takes the Band-Aid tin with him.
Mike drives to the site of the truck robbery and retrieves a metal detector and shovel from his trunk. He uses these instruments, along with the information supplied by Nacho, to find the body of the good Samaritan killed by Hector after the robbery. Mike anonymously reports the body to the Tribal police.
At his home, Chuck meets with Dr. Cruz, seeking to confront his EHS delusion and live a normal life again. Chuck is eager to recover quickly, but Cruz cautions him not to push himself too far. Chuck explains that he had a public "incident" which caused him to realize that his condition was in his head, and implies that the resulting epiphany caused him to reconsider his behavior.
Meanwhile, while preparing to film another commercial at the music store, Jimmy gets into a disagreement with the owners about pricing. When they refuse to pay him, Jimmy instructs Joey to keep his camera rolling and pointed at him. Jimmy drops a drumstick to the ground and, after confirming the owners refuse to pay, "slips" on the drumstick, falling flat on his back. He then begins his blackmail scheme.
While Kim is at lunch with Kevin and Paige, she sees Howard showing up with clients from HHM. Howard makes passive-aggressive small talk with Kim and her party. In response, she writes out a check to Howard for the amount of money covering her law school loans and presents it to him with a similar passive-aggressive interruption. After lunch, Howard confronts Kim and reveals that he has been forced to deal with the fallout from Chuck's performance at Jimmy's bar hearing. Kim points out that Howard withheld information about Chuck's condition from HHM's clients. Howard angrily rips up the check, telling Kim that her debt is forgiven but nothing else.
That night, Nacho goes into his father's upholstery shop and crushes ibuprofen tablets into a fine powder, which he carefully plants in the empty capsules that Daniel supplied him. He then practices slipping the pills into Hector's coat pocket. By the time morning comes, Nacho seems to have it down perfectly. When his father shows up, Nacho claims he came to work early to check on invoices.
Chuck decides that he needs to confront his EHS on his own. To that end, he walks to the local supermarket without any protection. Though the EHS does seem to kick in, Chuck manages to complete his shopping without incident. When he returns home, he finds Howard waiting outside. Howard is delighted and impressed that Chuck managed to shop by himself, but then reveals he's not here to make a social call: an issue has come up with Chuck's malpractice insurance.
Back at Wexler McGill, Kim finds Jimmy lying on his back in his office, playing on a guitar signed by Ritchie Blackmore, which we learn he received from the store owners through his con as well as selling them the remaining seven commercials as he had been trying to do. Despite Jimmy's assurances, Kim still expresses doubts about Jimmy's ability to cover his end of the expenses and considers taking on another client.
That night, Nacho climbs onto the roof of El Michoacáno and breaks the air conditioner; the restaurant is hot and sweaty the next day. As Nacho counts Krazy-8's money, he sees Hector take off his coat. Nacho pretends to scrutinize one of the bills in Krazy-8's stack, claiming that it looks "funny," possibly counterfeit or marked. Hector asks him to come over so he can scrutinize it. While Hector looks at the bill, Nacho reaches into Hector's coat left pocket but he doesn't find the pill bottle. He then "accidentally" drops the remaining money which allows him to take the pill bottle from the right pocket. Nacho returns to his seat and swaps the pills with the fakes that had been hidden in the satchel containing Hector's rubber-banded money rolls. He keeps the bottle on his lap while counting the next dealer's money, and is unusually short with him. Once this dealer is gone, Nacho performs the switch and tosses the bottle back into Hector's coat pocket as he walks by.
While picking up trash as part of his community service, Jimmy is handicapped by his back pain. A member of the work group, Freddy, asks the supervisor if he can take time off to visit his sick daughter in the hospital. The supervisor authorizes him to leave but warns him that he will not be credited with the hours he has worked. Having listened to the conversation, Jimmy instead deduces that Freddy is a drug dealer and that the excuse about his sick daughter is most likely a lie, but offers him a deal: for $700, Jimmy will make sure that Freddy can leave without losing his hours. Intrigued, Freddy accepts the deal.
Jimmy then lies on the ground to rest his back and the supervisor immediately reappears. Jimmy threatens to file a lawsuit against him for various, detailed reasons if he refuses Freddy to go see his daughter and Jimmy to rest his back, while allowing both to keep their hours. Panicked, the supervisor relents. Impressed, Freddy pays Jimmy and leaves. Jimmy continues to rest his back, satisfied with his particularly lucrative improvised ploy.
Late at night, Mike looks at the money he took from the truck robbery, removing it from the crawl space under his floorboards. Counting the stacks, he realizes there's no way he can spend this money without attracting suspicion. That night, he pays a visit to Gus in his office at Los Pollos Hermanos, asking him to launder the money so that Mike can give it to his family. He reasons that as Gus is running his restaurants for a similar reason, he might be able to assist Mike. Gus cautions that he and Mike can't be publicly associated given their rivalries with Hector, and the consequences that could come of this. After some negotiating, Gus proposes a potentially reasonable offer, upon which he and Mike shake hands.

- Jimmy: "Yeah, they worked hard: worked a lot of hours for a lot of years, for nothing."
- Marco: "I don't know Jimmy. A lot of customers, they liked him."
- Jimmy: "Everybody liked him because he was a soft touch. Every deadbeat in the neighborhood owed him money. You come in here with a sob story and you leave with a pat on the back and a gallon of milk. He could have made it work, he could have sold beer and cigarettes to the kids from Mary Margaret's, but no. Not him. He was never gonna do what he had to do."
