After being rather vague upon its initial unveiling, Netflix has lifted the lid on its new British documentary feature film about a chef who believes he’s found his long-lost mother but ultimately gets duped. The new documentary lands on our screens globally on March 25th, 2025. 

The story centers on the untold (which is definitely the case given there’s no coverage on this until this new Netflix doc) story of Graham Hornigold, a renowned pasty chef and the co-founder of Longboys Doughnuts. Until July 2020, he’d never known his mother, and out of the blue, he received an email from Dionne, who said she was searching for her son, who was taken away at the age of two. The story matches up. Making up for lost time, the duo live the high life until Hornigold suspects Dionne isn’t quite who she says she is after a few months.

BAFTA-nominated director Nick Green is behind the project, having previously worked with Netflix on one of the episodes for 2016’s docu-series Captive, which explored hostage situations and negotiations around the globe in addition to one of the. Other notable credits include Zuckerberg: King of the Metaverse, Carlos Ghosn: The Last Flight, A Dangerous Dynasty: House of Assad, and Putin: A Russian Spy Story. 

The documentary, which runs 1 hour and 28 minutes, will be released alongside a slew of other global docs slated for March 2025. Other notable titles include the Brazillian doc Larissa: The Other Side of Anitta, a new definitive take on Charles Manson titled Chaos: The Manson Murders, American Manhunt: Osama bin Laden, Twister: Caught in the Storm, and Gold & Greed: The Hunt for Fenn’s Treasure.

Elsewhere from Netflix’s UK division on the documentary front in 2025, we’ll see the release of Greenfall, covering the 2017 tower fire tragedy; Critical, a new series following first responders in a busy London hospital; and The Diamond Heist, a new docu-series produced by Guy Ritchie that follows the attempt to steal the £100 million Millennium Star Diamond from the Millennium Dome in the year 2000.
