A group of amateur footballers are trained up to compete against the might of a competitive senior football team. For the potential contestants to be an Underdog the criterion is simple: they cannot have represented their county beyond under-16 level! Once a final squad of players is selected by three former footballers through an exhaustive session of trials, the team are trained over six months at a special location. The series follows their progress as they prepare for the big day, culminating in a live final against an established side.
