In this episode, Pam's got a royal appointment at Highgrove Gardens, run by The Prince's Foundation and adjacent to the private residence of HRH The Prince of Wales, where Pam meets His Royal Highness himself. The Prince escorts Pam on a personal guided tour of his gardens to discover his passion for gardening and his vision behind the series of interlinked gardens that he's designed and nurtured over the past four decades. Along the way, His Royal Highness and Pam discuss his commitment to the environment and how sustainability is at the heart of everything he does at Highgrove. Pam also meets garden guide Emma Cochran-Patrick, and she gets hands-on with making traditional plaster decorative mouldings at The Prince's Foundation Barley Court workshop with Esme Walker. From Highgrove, Pam heads northwest and over the Cotswold border to the Forest of Dean, where she goes full steam ahead behind the controls of a locomotive on the Dean Forest Railway. Pam then heads to Tewksbury to tackle some prickly animals that have found themselves in a pickle. She's at the Vale Wildlife Hospital to meet the volunteers helping get poorly and injured hedgehogs back to the wild. And finally, Olympic rowing multiple gold medallist Sir Steve Redgrave takes us on a guided tour of another regal event, the Henley Royal Regatta.
