CEO Elaine is keen to say 'Croeso' to the world from their new premises. Elaine also visits a museum stockroom and gets up close and personal with the artefacts expert and his mummy. Elsewhere, Wales is gripped by Banksy fever following the discovery of his artwork in Port Talbot. Have Wyn and Charlotte managed to persuade the mysterious genius to create some bespoke art on the Wow Wales office wall? The whole staff are proud of the new premises, however, they have to contend with an environmental protester who is sticking to his principles and proving difficult to shift. Meanwhile, Gwilym attracts international recognition for his ultra-grim walking tour – the Trail of Tears.

Elaine passionately wants to promote Wales as the ideal location destination for screen projects – as a background, the Welsh landscape can look stunningly beautiful or ruddy awful depending on the requirements of the script! Wyn and Charlotte are proud to support a new feature film shooting in Wales. They undertake a set visit and are astonished at just how much they are permitted to see as the cameras roll! Wyn in particular needs a lie down afterwards. Meanwhile Nez contacts a 'white-hat hacker' to check the security of the Wow Wales website. He proves to be a genius at disrupting websites and a dunce at putting things back to normal. Plus Elaine samples the very latest in Welsh fusion cuisine when a genius contemporary chef opens a pop-up eating experience in a disused Cardiff washing machine factory.
