Our teacher used to show the class the same ten-minute 16mm b&w film over and over again… I think it was the only film they had… this was in the late sixties and the film was probably from the 1950s… a boy wakes up in a French coastal village but as he wonders about town there are no other children or adults to be found. He goes into an ice-cream shop and takes an ice-cream, leaving some coins on the counter as payment (I always thought this was rather pointless since everyone from the village had gone).
