Con Mumtells the story of renowned British pastry chef, and celebrity guest judge fromJunior Bake-off,Top Chef, andMasterChef: The Professionals, Graham Hornigold, who found adult success after a childhood that involved adoption, foster care, abuse at the hands of his biological father, and growing up without any information about his biological mother.

So when a stranger named Dionne reached out to Hornigold in 2020, claiming to be that missing mother looking to reconnect with her estranged son, he thought he had found the missing piece to his family tree.

The emotional stakes of their reunion are heightened by Dionnes alleged terminal illness, immense fortune, and claims to royal lineage as the illegitimate daughter of the former Sultan of Brunei.
