Listen up, Call the Midwife fans! The BBC has announced it's almost time to return to Nonnatus House for season 15 – and by the looks of the first pictures, it's set to usher in a whole new era of social change.
The new season, which lands on UK screens on 11 January, picks up after the dramatic events of the two-part Christmas specials and is set in 1971.
As someone who's seen a sneak peek of the first episode, I can promise you it has all the heartwarming, joyous and, at times, very moving elements that make this show one of the BBC's most successful and long-running series to date.
Plus, with a new era unfolding in the 1970s, there's plenty of new drama for the midwives to contend with, including the Women's Liberation movement, medical advancements and the question of where Nonnatus House sits within a modernising NHS.

Season 15 explores the Women's Liberation movement
What have the cast and creators said about Call the Midwife season 15?
Reflecting on creating what's set to be another stellar season, showrunner Heidi Thomas said: "Series 15 of Call the Midwife is one of our most exciting to date, and I loved every moment of writing it. Not only is the show now set within my own living memory – every time I see the Turner girls' outfits, I get a jolt of recognition – but 1971 sees the dawn of a whole new era."
Jenny has played Sister Julienne since the show's first season in 2012
Meanwhile, Jenny Agutter, who has played Sister Julienne since the show's inception in 2012, said: "I can't believe that we're on series 15 because in many ways, it feels like no time at all. It's 15 years of my life and how many changes there have been in my life in that time.
"Then, looking at the series – all the changes there have been in those 15 years as well. Social, economic, artistic, scientific and medical – all of those things change in the 15 years that we see on screen, which for me has always been the exciting thing about doing it."
She continued: "It's interesting because the series is always 50 years behind us and one's looking at it from a distance, and at the same time, you're comparing it with the world that you're in now, which is another world completely."
Call the Midwife returns to BBC One in the UK on 11 January and on PBS in the US on 22 March.
