Documentary series following a group of people through life. Every 7 years director Michael Apted visits to see how life has changed. This ninth installment finds the group aged 63.

We catch up with Bruce, the boarding school boy who was filmed, aged seven, missing his daddy. Growing up he longed to be a missionary in Africa but chose a teaching career in the UK instead. As retirement looms, he reflects on his life and work. We also pick up with Jackie who, at 56, was fighting cuts to her disability benefits as well as overcoming a series of family tragedies, including the death of her ex-husband. Has her life turned a corner? Finally, we meet with children's librarian Lynn, who we'd previously seen battling a life-threatening brain condition.

In the final episode, Paul and Symon - who were filmed at seven growing up in the same children's home - have an emotional reunion in Australia where Paul emigrated as a teenager. And we catch up with Neil, one of the series' most memorable characters who, as a seven-year-old in Liverpool dreamt of becoming an astronaut, but tragically in 28 Up was found homeless and struggling with mental health issues. Yet he surprised viewers in 42 Up when he reappeared as a Liberal Democrat councillor in Hackney. We catch up on the most recent chapter of Neil's extraordinary life.

Seven years after the first film, the children have all now reached the age of 14. The way their attitudes have changed, or have remained the same, is contrasted with clips from the earlier film.

The 'children' are now aged 21 and, although some of them have realised their earlier ambitions, others are leading quite different lives.

Michael Apted revisits the same group of British-born adults after a seven year wait. The subjects are interviewed as to the changes that have occurred in their lives during the last seven years since they were last seen in Twenty One Up.
