One Chance follows opera singer Paul Potts as a youngster growing up in Port Talbot and being bullied at school, meeting his future wife Julie-Ann, and working at a mobile phone store in Bridgend.
It shows how close he came to not even auditioning for Britain's Got Talent, back in 2007.
He was filling in an application form for the ITV show online and, struck with doubt, eventually flipped a coin to decide whether to enter.
Of course he went on to wow the judges with a performance of Nessun Dorma at his audition in Cardiff, and won the first series of the talent contest.
