First through the barn doors are Lloyd Richards and his wife Karen, with his father's professional Welsh rugby shirt from his playing days back in the 1960s. When Lloyd's dad died, Karen took it upon herself to try to score a try with the family and wash the dirty heirloom before they framed it up. She hadn't bargained for the 1960s cotton to not perform well at 40 degrees! The bright red of the beloved Welsh jersey ran into what was the crisp white collar. Things went from bad to worse when she then tried to bleach the now pink collar and ended up with marks over the entire garment. It's a tough tackle for textile conservator Rebecca Bissonnet, but her epic handiwork means it all comes out in the wash and instantly lifts the years off Karen's guilt. 

A much-loved but damaged large brass plate is the next item to arrive. Isha's heirloom, given to her mother around 45 years ago by a friend, once took pride of place at all her family gatherings as a serving plate for some delicious Caribbean feasts. But after Isha moved out of the big family house into a smaller home, the plate ended up stowed away in the garden for 15 years. Keen to revive the tradition of family and food for her two young kids, she's enlisting the help of silversmith Brenton West, who must even the dips out, get rid of the holes in the brass and bring the shine back to the plate. Returning to the barn with some mouthwatering treats for the gang, Isha's plate is transformed to its former glory days as the centrepiece of family life. 

It's a tale of animal rescue next in the barn. Pet lover Angie Bakalarou has the paper skills required for Hazel's map repair. Her dad was an RSPCA inspector who lived for his work rescuing animals all over Yorkshire. As a child, Hazel relished going with her dad on his call-outs. But these were the days before sat nav, and Hazel was put in charge of map-reading them to the right location - a job she adored. After her dad passed away, she found a single map of Wharfedale in his box of ‘important things to keep'. The map is now almost transparent, torn and with its edges falling apart, and Hazel's desperate to save it from ruin. Angie charts out the best route to recovery, leaving Hazel with the keepsake of her dad she had longed for. 

Irish musician Gary hopes professional organ restorer David Burville can put the wind back in his grandmother's beloved accordion. Back in the 1940s, it was her most treasured possession. She taught herself to play traditional Irish music by ear and performed at many a household ceilidh. Growing up, she taught Gary the importance of music in bringing people together, and when she died, when he was just 12, he was already hooked. Years later, graduating with a music degree and becoming a teacher himself, he's keen to see the old squeezebox restored. It's riddled with woodworm, and David's got plenty of fingerwork to contend with. But his mechanical, musical mastery results in a fully restored treasure which fills the barn with pure joy as Gary gives it a play.

The early birds at the barn are sisters Lottie and Amy, with a unique record of their childhood, a book given to Lottie as a Christmas present in 1976 when she was three years old. The sisters' mum, an English teacher, wrote it while their dad, an art teacher, did the illustrations. As Lottie says, ‘It's my most treasured possession still to this day.' The book charts Lottie's life from birth up to the age of three, including her sister Amy's arrival. It provides a snapshot of happy times before their parents divorced five years later. Now that their father has passed away, the sisters are keen to preserve the precious keepsake for the next generation. Bookbinder Chris Shaw and art conservator Lucia Scalisi tool up to restore the damaged book to its former glory. 

Next, arriving with a memento from his childhood, is Graeme, who has an unlikely heirloom in need of the metal-skilled minds of Dominic Chinea and Brenton West. Graeme's dad's old paraffin camping stove has put in the miles since it was purchased in 1957. It accompanied his parents on pre-kids cycling and camping trips, and later joined the whole family on walking adventures in the 1960s and 70s. But an explosion on a more recent trip has left the stove completely blown apart. Dom and Brenton take a two-pronged attack to get it back in action again, much to the delight of Graeme when he travels back to the barn. 

Next, a challenge for woodworker Will Kirk is posed by Melanie, who's brought a table that nods to her family's globetrotting past. The table belonged to Melanie's parents, who bought it in Thailand in the late 1960s. It then travelled around with the family as they moved homes multiple times. All family meals were taken around the circular table, with the food a fusion of her parents' English and Chinese heritages. The table is now dull and damaged, something Melanie is keen to remedy for the next generation. Will pulls out all the stops to bring the shine back to the family's table. 

The barn's final visitor, Mick, has a flat tweed cap, which belonged to his late father, for the attention of master hatter Jayesh Vaghela. Mick's father died when he was just 21, and the hat holds memories of the father he lost so young. His father, a bricklayer, wore the cap every day. It's a tricky fix for Jayesh, who needs to transform the cap without losing the very precious smell that connects Mick to his dad. What he does leaves Mick lost for words
