Children ski, sledge and have snowball fights on Hampstead Heath.
Title: "ST. MORITZ IN MINIATURE. Winter sports on the 'Hampstead Alps' for one day, and then came the thaw as usual!"
Various shots of children and young people tobogganing down a snow covered slope, they tumble off their sleds as they reach the bottom. M/S of small children pelting a policeman with snowballs. C/U of two boys on skis, other children play behind them. Various shots of the two boys skiing, they are watched by several adults - their parents and nanny, perhaps?
Note: the title is misleading - there are no shots of St. Moritz in this story.
