It's an emotional rollercoaster as Holly introduces us to Gary Bennett, who lost his wife and son in a tragic road accident in America. His nieces have also lost their mother, while years later, their father died from a heart attack.
Gary has raised his two nieces, Lydia and Ellie, alongside his children, Sarah and Leah, all on his own, and now they want to say a massive thank you to him for everything. We're blubbing already!
Also tonight, nine-year old Domenic from Cornwall will meet the man who donated his bone marrow to save Domenic's life, a lady who set up a social club for widowed men and women gets a special thank you, and a grandmother is nominated for a treat because of all the money she's raised for local charities.
