The first sequence opens with a street race in Ironwood where Darren Bowers races reigning champion Christian Maddox in a yellow Dodge Charger marked "UNB10." This race sets the tone for the town's deep connection to car culture and racing. Seventeen years later, Harris Bowers sits atop a bridge, receiving a call from Alice, who waits for him at Wade's Diner. Meanwhile, Samantha Torres drives her twin teenagers, Zac and Caitlyn, back to her hometown of Ironwood from Brooklyn. Samantha nostalgically recalls jumping off the same bridge in her youth, warning the twins not to follow her reckless path.

Upon arrival, the Torres family stays with Logan Maddox, a car customizer and Christian Maddox's brother. Logan shows off his latest work on a car bearing his signature logo, and Cate is eager to learn more about their missing father, Christian. Zac, however, is wary of revealing their connection to Christian, fearing the stigma it brings.

Zac practices driving at a junkyard with an old car named "Dottie," owned by Buzz, who advises him that racing requires knowing whether to accelerate or brake in critical moments. Ray, a local gang leader, asks Logan to drive for his crew during a heist, but Logan refuses. At school, Harris is grounded and without his car, so Alicia drives him. Curtis helps Cate restore the "UNB10," Christian Maddox's old racecar, and seeks vintage parts from Ray, who demands Curtis's help on a job in exchange.

During Ironwood's annual Fireflies Festival, Cate and Curtis grow closer, and Kiara, the mayor's closeted daughter, shares a tender moment with Cate. Marcel reveals his new racing logo, but Zac loses a street race, crashing Marcel's car. That night, Ray and his gang attempt a robbery during the festival blackout, but police interference limits their success. In retaliation, Ray's gang destroys Logan's classic Mustang.

Cate, Zac, Curtis, and Marcel jump off Ironwood's bridge as a rite of passage, but tensions rise when Marcel blames Zac for wrecking his car. Underwater, a necklace sinks, revealing Christian Maddox's long-lost car at the river's bottom, hinting at deeper mysteries.

In the past timeline, Hugo and Ezra, members of Ray's heist crew, flee from police after a failed job. Ezra is injured and refuses hospital care to avoid prison, reflecting the dangerous lives the older generation led.

Harris challenges Zac to a street race, while Cate insists they need three weeks to prepare, though they actually require three months to restore the car properly. Zac's driving skills improve under Buzz's guidance, but the pressure mounts as the race approaches.

Ray's gang continues to exert control over the town's underground activities, forcing alliances and betrayals. Logan remains conflicted about his involvement, torn between protecting his family and staying out of crime.

Next, Harris tells Zac where to find a rare car, the UNB10. Zac visits Ray's chop shop to claim the car he won in a previous race. The two brothers then meet for a private race on a deserted street. Zac, having walked the route earlier, knows where the hazards lie. Harris, unfamiliar with the road, hits a pothole, causing his car to skid, overturn, and catch fire. Zac stops his car and rushes toward Harris but freezes when he sees the flames engulfing the vehicle. The scene ends ambiguously, with Harris's survival uncertain and Zac emotionally paralyzed.

Meanwhile, Curtis, who has learned that his father was involved in Christian Maddox's disappearance, begins to distance himself from Cate. Cate, encouraged by a mentor figure named Dottie and a friend named Buzz, decides to pursue Curtis despite the complications. She kisses Curtis, but when he confesses the truth about his father, Cate's expression changes, signaling a fracture in their relationship. Curtis declines an invitation to New York from Brooke, who then invites Marcel instead. The episode closes with Curtis and Cate not speaking, highlighting the emotional fallout from the revelations.
