Released on March 25, 2025, this documentary is the latest addition to Netflix’s collection of captivating scam stories that captivate viewers from the outset. We’re talking about Graham Hornigold, a big-name UK pastry chef, who thought he’d hit the jackpot reuniting with his long-lost mom—only to get tangled in a jaw-dropping con. At TV Acute, we are passionate about delving into unconventional narratives such as this one, and Con Mum is a compelling example. Let’s dive into the madness of this Con Mum Netflix true story and why it’s worth your next binge.
What’s Con Mum All About?
In 2020, Graham Hornigold, a successful pastry chef at upscale establishments such as Hakkasan and a judge on Junior Bake Off, receives an unexpected email that completely changes his life. A woman named Dionne says, “Hey, I’m your mom!” She claims she lost him as a kid in Germany and has been searching for him ever since. Graham, having experienced a difficult childhood without his biological mother, is ecstatic. He fires back some personal questions—stuff only his real mom would know—and Dionne nails every answer.
Soon, they’re meeting up in Liverpool, and it’s all hugs and instant bonding. But here’s where it gets juicy: Dionne drops that she’s got a brain tumor and bone marrow cancer, with just six months to live. Oh, and she’s loaded—think private jets, luxury hotels, and a story about being the secret daughter of the Sultan of Brunei. She’s promising Graham a fat inheritance, and he’s buying it hook, line, and sinker. Sounds like a fairy tale, right? Well, keep reading, because this Con Mum Netflix true story takes a dark turn.
The True Story Behind Netflix’s Con Mum
So, Graham’s all in. Graham and his partner, Heather, embark on a luxurious lifestyle with Dionne. She’s booking them into swanky spots like The Dorchester in London (owned by the Brunei royal family, no less), where staff greet her like she’s VIP. She even buys Graham and Heather brand-new Land Rovers—pretty sweet, huh? Then she whisks Graham off to Switzerland to sign papers with bankers and lawyers to lock in his inheritance. What was supposed to be a quick trip turns into weeks, and that’s when the cracks emerge.
Heather notices huge chunks of cash vanishing from their joint account. Turns out, Graham’s been footing Dionne’s bills—hotels, champagne, you name it—thinking she’ll pay him back once her “fortune” comes through. Credit cards in his name start racking up debt, and before long, they’re out hundreds of thousands of pounds. Meanwhile, Dionne’s in Zurich, sweet-talking other folks into “investing” with her, swearing them to secrecy with lines like, “Don’t tell Graham.” Sneaky, right? The deeper you dig into this Con Mum Netflix review, the wilder it gets.
Why Did Graham Fall for It?
Let’s back up a sec—why was Graham so quick to trust this woman? The guy’s got a story that’ll tug at your heartstrings. Born on a British army base in Germany, he was fostered out at age two for reasons he still doesn’t get. At four, he lands with his dad and stepmom in St. Albans, England, but it’s no happy ending. His dad’s abusive—think beatings over spilled tea—and Graham grows up angry and hurt. He cuts ties at 18, never looking back, but that longing for a real family never fades.
Enter Heather, his rock. They meet, bond over baking, and build a life together—business, love, even a baby on the way. But Graham’s still got this hole inside him, wondering about the mom he never knew. His birth certificate lists a “Haton Hornigold,” but searches lead nowhere. When Dionne’s email lands during the COVID lockdown, it’s like a lifeline. She is aware of details, such as his German birth, that solidify his connection with her. Who wouldn’t want to believe they’d found their mom after 40 years?
The Big Reveal: Dionne’s a Pro Con Artist
Here’s where Con Mum gets insane. Dionne’s not just playing Graham—she’s a seasoned scammer. She’s got a trail of victims, like Peng, a Chinese businessman who saw her as a grandma figure. She promised to fund his business, and he shelled out cash and gifts—money she used to bankroll her luxe life when she met Graham. Then, she charmed Markus and Junyan, another couple who lavished large sums of money on her. She even faked needing rare cancer surgery in Switzerland, conning Peng into paying for it. Spoiler: no tumor, no cancer—just lies.
Back in England, Graham’s life is falling apart. Dionne’s keeping him from Heather and their newborn, draining their savings, and sticking them with car payments. When Heather catches on, it’s too late—they’re broke, and Graham’s crushed. But the kicker? He demands a DNA test, and—plot twist—Dionne’s actually his real mom. Yep, the woman who scammed him out of everything is the one he’d been searching for his whole life. It was truly devastating.

How Did Dionne Pull This Off?
Dionne’s a master at this game. Back in 1982, she was busted for fraud in England and pleaded guilty. Instead of cleaning up, she bounced to Malaysia, tweaking her scams. She’s duped people there too—think fake Haj pilgrimage deals—and when COVID hit, she ran out of marks. That’s when she Googled Graham, saw he’d made it big, and pounced. Her sob story, the Brunei royalty incident, and the chummy behavior of the hotel staff are all fabricated. The Dorchester staff probably just knew her as a regular who tipped big (with other people’s money). She excels at maintaining a professional appearance while taking advantage of others.
