On 25 September 2021, thousands of dead and dying crabs and lobsters washed up along the Yorkshire and north-east coastline. Hours earlier, a major dredging operation had disturbed sediment at the mouth of the River Tees — sediment that had absorbed decades of toxic industrial discharge. The authorities called it an algae bloom. Then a novel pathogen. The fishers called it what it looked like. Jeanie Finlay does not arrive with a verdict. 'I can't offer an easy answer to what happened,' she says plainly. What she can do — and what All Rivers Spill Their Stories to the Sea does with quiet force — is show you what four years of institutional denial does to the people who bear its costs. That is a harder, more honest thing than a prosecutorial documentary would have been. Stan Rennie is the film's centre of gravity: a fisherman who spent decades practising conservation before he ever called himself an environmentalist, v-notching large female lobsters and returning them to sea so they'd never be legally catchable. 'We could have landed thousands of lobsters,' he says. 'But we thought we were doing our bit.' Then overnight, everything was dead, and all those years of stewardship had nowhere left to stand. That specific detail — the v-notched lobsters, the 50-year lifespans, the careful practice obliterated in a single event — is what separates this film from a generalized grievance story. The antagonist, never framed as a villain but functioning as one structurally, is Ben Houchen, then Tees Valley mayor and now Conservative Lord Houchen. He presided over the fast demolition of the old steelworks — the UK's largest controlled explosion in 75 years — and the rapid construction of the Teesside Freeport in its place. His consistent refusals to engage with the fishers, his labelling of them as 'activists,' and his denials as evidence accumulates are the film's slow-burn source of fury. Finlay does not editorialize. She does not need to. The Mr Bates comparison, coined by Tina Brown, is apt in structure if not in scale. This is a story of working people whose livelihoods have been erased, who lack institutional power, and who are doggedly assembling evidence that the official account cannot hold. What ITV's dramatization of the Post Office scandal demonstrated — that storytelling can shift what feels possible — is part of the film's own backstory: the NEFC fishers only agreed to be filmed after Mr Bates vs The Post Office aired. They had started to believe nothing would change. Then they watched what a story could do. Finlay's edge here is not objectivity but proximity. She grew up in Stockton-on-Tees. She knew the coastline before she knew the story. That rootedness gives the film something most eco-documentaries lack: the texture of a specific place mourned by specific people, not an abstraction called 'the environment.' Dr Sue Wilson watching every seal pup born along the coastline die. Dr Simon Gibbon, a chemist, trying to get the dredge licence put on hold. These are not supporting characters in a policy argument — they are people whose professional and emotional lives have been reorganized around a question the authorities refuse to officially answer. The film opened to festival recognition at Bristol and Mediterrane, and has driven real-world consequence: a £100,000 NEFC fundraiser for the next round of scientific testing filled during screenings, including a £1,000 donation from a stranger in Glasgow during a Q&A. Mark Kermode called it 'a life-affirming treat — funny, poignant and profound.' That is not hyperbole. Finlay has made something that earns its emotion through specificity, not manipulation, and that lands in cinemas on 23 October.
