Mrs Beryl Swain is a housewife with an unusual hobby for a woman - she competes in motorcycle races. We first see Beryl out shopping with a friend. She looks into the window of a baker's shop. Footage of motorbikes being polished. C/U of Beryl putting on a crash helmet. We see Beryl moving off towards the start line. Various shots of bikers waiting for a race to start. Shots of the race and of spectators. Beryl seems to do quite well. Beryl's husband watches her progress.
