Underwater shots at the Aldershot Lido show frogmen sawing wood and hammering stakes, to prepare the pool for a game of underwater hockey. Men on the side of the pool put on diving equipment and snorkels. The referee tosses a coin and the players all jump into the pool, watched by a rather bored looking small crowd.
The ref blows a whistle and there follows a lengthy underwater sequence where it is quite hard to see what is going on; the men seem to be pushing a puck along with little paddles. High angle shots show the frogmen frantically scrabbling about in the water - not that interesting for spectators, though a few look more animated now.
Note: the underwater sequences are quite scratched.
