Seaside Postcard is a comedy for four men and four women, originally presented by the Young Vic Company, London. The group assembled on the beach could almost be regarded as characters from typical seaside postcards brought to life. During their brief sojourn much happens. Terry, heir to three fish and chip shops, becomes engaged to Sharon but anticipates marriage with her; the meek worm Martin suddenly turns; an unfortunate explosion shatters the sunbathing calm, a wife-swapping seems imminent and a rising tide threatens the lot of them.
