Greg Davies's father made sure that his son was born on Welsh soil so that when Greg became a rugby international, he'd play for Wales. Fortunately for comedy, Greg showed little talent for rugby; but he retains a sense of connection to his Welsh ... (more)roots and, two years after his dad's death, wants to know more about them. Greg gets more than he bargained for when he identifies a wayward great grandfather, but is rewarded when the trail leads further back to the deepest, Welsh-est roots that anyone could wish for.
