Welsh world champion and Olympic sprinter Jamie Baulch goes in search of his biological father who he believes to be Jamaican and the source of his speed. In the previous Bafta Cymru-winning documentary two years ago, Jamie, who is adopted, went on an incredibly emotional journey looking for his birth mum. In the end, he found her, met her for the first time and showed her his athletic medals. Picking up from the last film with the meeting of his two mums, Jamie then hits the streets of the black community in Nottingham, the city of his birth, to find his natural father. He questions whether his athletic talent is in his genes or a consequence of his determination and upbringing - his parents, his teachers, his coaches? Nature or nurture.
