The series "Motorheads" begins with a flashback to a street race where Darren Bowers competes against Christian Maddox, the reigning champion, in a yellow Dodge Charger with the number plate "UNB10." This race is part of a bet, though the specifics of the wager are not disclosed. Seventeen years later, the story shifts to Harris Bowers, who is sitting on a bridge, receiving a call from Alice asking where he is. Meanwhile, Samantha Torres and her twin teenagers, Zac and Caitlyn Torres, are driving into Ironwood, their hometown, after moving from Brooklyn. Samantha shares stories of her youth, including jumping off the bridge, which Zac and Caitlyn find hard to believe.

Upon arrival, they meet Logan Maddox, Christian's brother, who customizes cars in a garage next to his house. Logan is welcoming and shares some stories about Christian, which excites Caitlyn but makes Zac cautious about revealing their connection to Christian due to his troubled past. Zac and Caitlyn start at a new school, where they meet other characters, including Harris Bowers, the son of the formerly wealthiest man in Ironwood, who is struggling with his mother's recent death.

As the series progresses, Zac practices driving at a junkyard with a battered car named "Dottie." The junkyard owner, Buzz, advises Zac on the importance of knowing when to accelerate or brake in racing. Meanwhile, Ray asks Logan to drive for his crew during a heist, but Logan declines. At school, Harris is grounded and loses access to his car, forcing Alicia to drive him. Curtis helps Cate with restoring the UNB10, Christian's old racecar, and seeks vintage parts from Ray in exchange for help on a job.

During Ironwood's annual Fireflies Festival, Cate and Curtis grow closer, and Kiara, the mayor's closeted daughter, shares a moment with Cate. Marcel reveals his new racing logo, and Zac loses a street race, damaging Marcel's car. That night, Ray and his gang attempt a robbery under the festival blackout but are thwarted by police interference. In retaliation, they vandalize Logan's classic Mustang. Cate, Zac, Curtis, and Marcel fulfill a promise by jumping off Ironwood's bridge. Tensions rise when Marcel blames Zac for his broken car. Underwater, a necklace sinks, and Christian Maddox's long-lost car is revealed at the river's bottom.

In the past, Hugo and Ezra, members of a heist crew, flee from the police. Ezra is injured and refuses to go to the hospital, fearing imprisonment. He asks Hugo about his son Ray's activities. This storyline intertwines with the present as characters navigate their relationships and the mysteries surrounding Christian Maddox's disappearance.

As the season unfolds, Harris challenges Zac to a street race, and Cate suggests they need three weeks to prepare, though in reality, they need three months. The season culminates with Harris trapped in a fiery car crash during a race, leaving his fate uncertain. Throughout the season, the characters navigate love, loss, and identity while dealing with the pressures of high school and the dark past of their town.

The first season of Motorheads ends with a dramatic and ambiguous climax: Harris crashes his car after hitting a pothole during a race against Zac, and the car bursts into flames. Zac approaches but hesitates to help as the car burns. Meanwhile, the mystery of Christian Maddox's disappearance is revealed--he likely faked his death to protect his family from the dangerous racing world. Other character relationships, such as between Curtis and Cate, face tension and unresolved issues. The season closes with Caitlyn receiving a mysterious phone call, leaving several storylines open for continuation.

The ending unfolds scene by scene as follows:

The finale opens with a flashback to the day of a robbery involving Christian Maddox and Samantha, who helps bury stolen money at a secret spot. This sets the stage for the unresolved mysteries surrounding Christian's fate.

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.

Zac and Alicia's relationship remains unresolved; Alicia gave Zac a code related to the heist, but they do not interact in the finale. The final moments show Caitlyn receiving a mysterious phone call from Spider Lake, Michigan, hinting at new developments and mysteries to come.

The truth about Christian Maddox is revealed through the siblings' investigation: Christian did not die in the crash as everyone believed but faked his death to protect his family from the dangerous underground racing world. This revelation ties together many narrative threads and underscores themes of legacy, sacrifice, and the cyclical nature of the characters' lives.
