In a flash-forward, we hear heavy breathing and see a broken pair of eyeglasses on the floor. Blood drips onto the floor and on to a familiar pair of Wallabee shoes. A man's hand struggles to pick up the glasses. Upon retrieving them, he slowly stumbles away.
Walter White drives Hank Schrader to Los Pollos Hermanos. Though he's unaware Tyrus Kitt is tailing them, Hank senses Walt's anxiety and attempts to lighten the mood by humming the theme song from Rocky III. Walt retrieves the GPS locator from Gustavo Fring's car but refuses to enter the restaurant this time, much to Hank's annoyance who was hoping for a vanilla milkshake. Back home, Hank curses when the GPS data reveals that Gus only made trips between home and one Los Pollos Hermanos location. He's either squeaky clean, suspiciously so, or very careful. Leaving Hank's house, Walt spots Tyrus surveilling them. He pulls up to Tyrus' car and calls 911 to report a suspicious man in the neighborhood, forcing Tyrus to leave.
Outside the Lavandería Brillante, Walt is mildly taken aback when Jesse Pinkman says that he's already started the cook. Walt bums a cigarette and sees the ricin still in Jesse's pack. Jesse insists that he still intends to poison Gus. Walt lights his cigarette over Jesse's disapproval.
That evening, Skyler White calls Walt from the car wash and suggests that they buy Walter White Jr. a used car for his sixteenth birthday. Walt agrees without enthusiasm. Skyler then reports that the "profits" are so good that Walt could begin preparing an exit strategy from his second job. Walt, however, knows that there's no way out as long as Gus is alive.
The next morning, Hank calls Walt and proposes a drive out to what Hank theorizes is Gus' meth distribution center. Knowing that Hank means the Los Pollos Hermanos Factory Farm, Walt feigns illness and convinces Hank to delay the trip; he then calls and warns Mike Ehrmantraut. At the factory farm, Mike directs Jesse and other operatives to hide all evidence of meth distribution.
Meanwhile at the car wash, Skyler makes false purchases between actual customers, to help account for all the extra money Walt's giving her. Ted Beneke then visits Skyler and tells her that the IRS is auditing his business. As the bookkeeper of record, Skyler realizes that a criminal investigation would permit agents to monitor her mail and phone calls, and probably open the books at the car wash—a disaster across the board.
Back at the farm, Jesse muses to Mike about the potential fallout that offing Hank could give, given his connections to both the DEA and to Walt, who would surely stop cooking. Mike asks if Jesse would have a problem if something happened to Hank. Jesse replies that no one cares what he thinks. Outside, a sniper suddenly kills one of Mike's operatives. Furious, Gus walks straight toward the gunfire as bullets continue to explode around him, with it being obvious that the sniper is deliberately missing. Mike calls for him to stop, but Gus instead stalks toward the gunman's position, defiantly raises his arms, and stands in plain view. The shooter turns out to be Gaff, the thug who delivered the Cartel's ultimatum, armed with a Remington 700 (""). He stops shooting, and smiles.
That night in his Los Pollos Hermanos office, Gus receives a call. Mike and Jesse arrive at the superlab to dispose of the shooting victim's body. Walt sarcastically asks if corpse disposal is a new sideline before launching into a diatribe against Gus, whom he assumes ordered the man dead as punishment or to send a message to him again (both false). Mike in response tells him to shut up and warns him against ever calling the police on one of his men again or he will be killed. Outside the laundry, Jesse asks Mike why Gus did what he did at the farm. Mike explains that Gus knew the Cartel wouldn't kill him, because they need his distribution system. Jesse takes this to mean that he and the rest of Gus' operatives are open season. Mike suggests that Jesse speak with Gus directly about any questions he has.
The next day, at the IRS building, Ted is in a meeting with his investigator, Special Agent James Picarus of the Criminal Investigative Division. Ted fumbles his way through his audit until Skyler unexpectedly appears. Dressed in a revealing outfit, Skyler explains Beneke Fabricators' unreported income: As a paper person, she didn't record electronic payments because there wasn't a physical check. James assumes as Skyler intends and buys the act. Outside the building, Skyler says that her stunt spared Ted jail time because 'ignorance' doesn't constitute criminal fraud. He just has to pay the back taxes and penalties—to the tune of several hundred thousand dollars. When she sees that his car is a used subcompact instead of his BMW, Skyler realizes that he's not kidding.
That evening, Jesse has dinner at Gus' house. While Gus chops vegetables, Jesse stands next to the pot of stew with the ricin cigarette in his hand, but can't bring himself to go through with it. Over dinner, Gus agrees to address Jesse's concerns, but only after Jesse answers if he can cook Walt's formula. Jesse accuses Gus of playing the part of his buddy so Jesse can take over after Gus murders Walt, and says that if he kills Walt, he'll have to kill him too. Gus calmly responds that is not what he meant, then explains he needs Jesse's help to prevent an all-out war with the Cartel.
Unable to sleep that night, Skyler looks pensively at the vacuum-sealed bags of money under the house. After work at the superlab the next day, Walt removes a GPS locator that he planted on Jesse's car. At the condo, Walt examines the data, which reveals the trip to Gus' house. Meanwhile, Jesse leaves a message on Walt's voicemail that he has something important to tell Walt.
Walt drives to Jesse's house, where Jesse in a panic announces that to avert an all-out war, Gus wants him to travel to Mexico and teach Cartel chemists Walt's formula. Fearing that he'll fail and be killed, Jesse begs Walt to coach him. Walt asks several times if Jesse has seen Gus, which Jesse guiltily denies. Walt grabs the cigarette pack out of Jesse's pocket and finds the ricin still there.
Jesse yells at Walt, and Walt argues that Jesse has only signed Walt's death warrant. Jesse snaps and throws the GPS device at Walt, leaving a deep wound on his brow. Walt lunges at Jesse and a vicious, brutal fight ensues. Jesse eventually gains the upper hand, pinning Walt to the floor and repeatedly punching his face, breaking his eyeglasses. We've now caught up with the flash-forward teaser. The fight over, Jesse asks if Walt can walk. When Walt nods yes, Jesse stares at him coldly. As a bloodied Walt exits, he looks over at Jesse, who turns away without a word.
