In 2008, a fragment from an asteroid plummets into Peckham, London and collides with Robert 'Bob' Kenner, a mild-mannered, socially awkward postman who keeps to himself more than most people would admit. The impact jolts him with extraordinary abilities, and at first he tries to figure out how to control them on his own. A reckless moment—crashing into The Shard—forces him to surrender to the authorities, setting in motion a strange path from everyday guy to something far more legendary. Trained by the Ministry of Defence, Bob](/actor/brett-goldstein) emerges as SuperBob, the world’s first superhero who technically works for the MOD and the British Government as a civil servant, a status that both constrains and empowers him in equal measure.
Six years pass, and Theresa](/actor/catherine-tate), Bob’s ruthless boss, greenlights a documentary that aims to present SuperBob as a normal man rather than a weapon of state power. In Peckham, Dorris](/actor/natalia-tena) — a caretaker who also keeps watch over Bob’s mother — and Pat](/actor/ruth-sheen), Bob’s mother, form an intimate circle around him. Bob and his friends live simply: Barry, the ever-watchful security guard, helps keep the peace, and Dorris builds toward a dream of a nursery in Colombia. The footage crew follows Bob as he explains he takes a day off every Tuesday and confesses that he’s planning to go on a long-awaited first date in six years with a librarian named June](/actor/laura-haddock).
A routine shopping trip with Dorris becomes a turning point when an urgent call from Theresa] interrupts their plans, pulling Bob into a meeting about meeting the American delegation. The summit features Senator Jackson](/actor/martin-mcdougall), a high-profile guest who views SuperBob as a dangerous, uncontrollable asset—part of a smear campaign launched when the U.S. government failed to recruit him previously. Yet, after talking with June and heeding Dorris’ steady counsel, Bob defies orders and heads toward the date anyway. A sudden care-home emergency interrupts the plans again, and a misunderstanding leads Bob’s mother to briefly think that he and Dorris are an item, underscoring the fragile line between personal life and public duty.
The dinner with June is set to be interrupted once more when the two are taken to the MOD for the Weapons Summit. June reveals that Theresa blocked her lunch with Bob and that, despite her own feelings, Theresa and the MOD want him paired with June because she is American. Yet when Senator Jackson shakes his hand, Bob learns the darker truth: the U.S. government has funded a nursery for Dorris and intends to send her away. Anger spikes as Bob feels manipulated, and he shatters the MOD roof in a dramatic escape, triggering a worldwide manhunt as sightings of the runaway superhero flash across the globe.
Determined to find Dorris, Bob tracks her to a care home where locals block police entry, driven by their affection for the pair. He convinces Dorris to accompany him to Colombia, chasing her dream of helping children and choosing a life outside the constraints of official power. As the world watches, Bob resigns from the MOD and announces he will go freelance, declaring himself no longer the property of the UK and offering his number for those who need help. He says goodbye to Theresa](/actor/catherine-tate) and to Pat, and Dorris](/actor/natalia-tena) and Bob leave together in the night.
In the closing moments, we see Bob](/actor/brett-goldstein) and Dorris(/actor/natalia-tena)) thriving in Colombia, their bond steady as they relocate with Barry to pursue a life built on mutual aid and real-world good. The world’s eyes look on as Theresa](/actor/catherine-tate) is reassigned to Afghanistan, and scientists comb the meteorite for six years in the hope of tracing the source of SuperBob’s powers—without success. The film leaves us with a portrait of a man who learned to harness power without losing his humanity, choosing partnership and purpose over the easy path of control and recognition.
- The tone throughout stays grounded and observational, letting the extraordinary premise unfold through Bob’s decisions, his relationships, and the quiet, stubborn belief that one person can make a difference without becoming a weapon. The supporting cast—Pat](/actor/ruth-sheen), Dorris](/actor/natalia-tena), June](/actor/laura-haddock), and Barry](/actor/ricky-grover)—provides texture to Bob’s world, a mosaic of ordinary life intersecting with extraordinary capability. The narrative balances moments of humor with intimate scenes of doubt, sacrifice, and brave defiance, never losing sight of the core question: What does it mean to be a hero when the people you care about most are the ones who stand to lose the most?
