The children of Barton United are trying to win the cup in their local football (soccer) league. Nasty councillor Mr Bates doesn't like them and wants the team his son plays for to win instead so he makes life as difficult as he can for them. But Barton United are offered help by the local professional team that just happens to be Manchester United with boss man Matt Busby.
The police and the local soccer team join with a children's team to foil the nefarious schemes of a shifty local politician. Not very interesting, though kids will enjoy it.
