Harold Makepiece, a redundant Civil Servant, while taking a quiet holiday at the seaside, gets into conversation with Joyce, whose main preoccupation is feeding sparrows, in whose welfare she seems to take a somewhat exaggerated interest. What starts as an odd but moderately reasonable exchange gradually turns into a nightmare as Harold becomes involved also with a freakish Edward and the seaweed-eating Sandra. It turns out that all three are planning to bomb a large power station nearly because of the pollution it causes. They try and rope in Harold as an accessory, until events are taken out of all their hands in a totally unexpected way.-2 women, 2 men
