Call the Midwife’s Heidi Thomas reveals season 15 “brings era to an end” – and why it was “hard” to write

Okay, so Season 15 really throws Nonnatus House for a loop. It’s a tough time for the sisters – they’re facing pressure from the NHS to modernize, and that includes a big ask: potentially giving up their traditional habits or losing funding. On top of that, things are changing with how people view healthcare in general, and Nonnatus House is right in the middle of it all. It’s a season about adapting, and it’s definitely putting everyone to the test.
