A seized-up ventriloquist's dummy that's over 100 years old receives a much-needed makeover, while a revived cornet brings back precious memories. Also undergoing triumphant transformations are a Roman-style leather chair and a one-off, handmade notebook recording information gathered whilst birdwatching.

Getting to work first is organ restorer David Burville, who has an appointment with George, an 1890s ventriloquist's puppet, one of the barn's more idiosyncratic visitors, accompanied by his owner Alison. Alison has brought George to see David with a request that this once dapper young gent can be transformed from his now rather worn and tatty state. Alison has had George since she was an 11-year-old girl struggling at school due to undiagnosed dyslexia. George gave Alison an outlet for her creativity and personality that she credits with helping her grow in confidence as a child. But now George is broken, both on the outside and the inside. His face is scuffed and chipped, the inner workings that move his eyes and mouth have seized up, and his once snazzy suit is ripped and moth-eaten. It's clear George needs a lot of attention, so both Kirsten and the teddy bear ladies come to David's aid, offering to fix up George's face and outfit while David delves inside to restore George's expressive face and mouth movements.

Next to arrive is Lewys from south east Wales, who has brought with him a very precious instrument handed down from his grandfather. A brass cornet, dating from 1897, belonged to Keith, a bandleader in a small Welsh village, and was inherited by Lewys after his grandfather passed away on Boxing Day 2021. Lewys spent hours learning the instrument under the tuition of his grandfather, and the cornet holds incredibly precious memories of his grandpa Keith filling the house with music. But in his later years, Keith was unable to play the instrument, and its once vibrant exterior is now dull and dented. Lewys is hoping that musical instrument expert Pete Woods can get the cornet back into the perfect condition for it to be proudly played once again.

Arriving for an appointment with skilled upholsterer Sonnaz Nooranvary is Nick from Somerset, who has brought along the broken remains of a Roman-style chair that belonged to his late father Richard. With the ornate leather and timber chair in pieces on the table, it's clear Sonnaz has her work cut out. Nick explains that he grew up on a farm, largely raised by his dad after losing his mother at the age of just six. Nick's father was a hard-working man who still made time for his family, and Nick has fond memories of sitting on his father's lap in the Roman chair after Sunday lunch and listening to him tell stories and entertain the family. Sadly, Nick's father was diagnosed with cancer and passed away whilst Nick was at boarding school aged 11. The chair is a poignant reminder of the beloved father who taught Nick so much about life, but now it's in several pieces, with badly worn leather and a missing leg. Sonnaz commandeers furniture restorer Will Kirk to recreate a new leg and fit the unique X-shaped chair-frame back together whilst she painstakingly removes the original leather and stud work, retaining as much of the original as possible.

The last visitor to the shop is Kat, who hopes that book restorer Chris Shaw can bring his considerable talents to the restoration of a handwritten notebook that once belonged to her grandmother Mildred. The notebook, which Mildred started in the 1940s, is a catalogue of local wildlife and birds, complete with her own drawings and even feathers she collected. Kat credits her grandmother with instilling in her the same love of nature, and the two would often spend hours wandering Kew Gardens spotting birds and enjoying the outdoors. It was a pastime that Kat enjoyed up until her grandmother's death in 2020. When Mildred passed away, Kat found it hard to find the enthusiasm for birdwatching, until the notebook was discovered amongst Mildred's belongings. Now Kat would like Chris to strengthen the book, which is falling apart, so that she can reconnect with the memories of her grandmother and maybe even add some of her own bird sightings to the notebook to continue her grandmother's legacy.

To celebrate 75 years of the NHS, the team revives four precious items chronicling the evolution of the publicly funded healthcare system founded in 1948.

First to arrive are two nurses who have devoted their working lives to the NHS. Approaching retirement, Catherine is the longest-standing staff member on a children's ward at Frimley Park Hospital in Surrey, while Katie is the senior sister on the same ward. They need the expertise of metal man Dominic Chinea to get their hospital food trolley back on track. The Thomas the Tank Engine trolley provides light relief for sick children as it's wheeled into the ward three times a day to serve breakfast, lunch and dinner. It's been a feature on the ward for more than 30 years, but it is starting to show its age. It's full steam ahead for Dom who needs to get the trolley back to the hospital as soon as possible for the children to enjoy.

Next, the barn team welcomes a very important visitor who owes his life to the NHS, children's author and poet Michael Rosen. He's hoping bookbinder Chris Shaw can repair the daily diary kept by nurses and carers whilst he was in a 40-day induced coma at the start of the pandemic. The modern spiral notebook is Michael's record of this time when family members were unable to visit. The hospital staff were the only people in close contact with him and used the diary to relay what was happening to Michael day by day. The patient diary was gifted to him when he was finally discharged from the critical care unit. Along with the notebook, Michael has brought the many letters, drawings and notes that his young fans sent to him while he was in hospital. Currently being stored in a messy bundle, Chris gets to work to create a more fitting tribute for the thoughtful artwork, leaving the usually eloquent Michael momentarily lost for words.

Next into the barn are Dr Adrian and his daughter Lydia with a 1960s GP's bag holding memories of Adrian's late father Noel. Born in Burma, Noel attended medical school in the 1950s but came to the UK in the 1960s to escape the military regime. Once here, Noel found work as a GP and spent his entire career dedicating himself to the NHS. His son also became a GP, and his granddaughter Lydia is currently training to be a dentist, meaning his lifetime dedication to healthcare lives on in his family. Leather expert Suzie Fletcher joins forces with silversmith Brenton West, who needs to get Noel's old medical instruments back in working order.

The barn's final visitors are another NHS family. Husband and wife Bill and Kate and their daughter Fiona have all worked for the NHS. They've brought along an old wooden desk that Bill saved from being thrown away when he was a student at nursing school in 1987. Bill went on to do all his studying at the desk and subsequently spent 37 years specialising in mental health. His wife Kate has worked for many years as an NHS administrator, also using the desk to study for her own qualifications. Now daughter Fiona is working as an occupational therapist in an NHS community mental health team, something that makes her parents very proud. Woodwork whizz Will Kirk is tasked with revamping this important little desk in tribute to their hard work.
