A timid bank clerk, middle-aged Leonardo arrives in the seaside resort of Sitges on the eve of his wedding. He is to marry Loli, owner of a souvenir shop, but first he'd like to indulge his fantasy of seducing a barely bikinied babe on the beach. Abandoning his ailing mother to her plastic swimming pool, Leonardo heads for the shore where Swedish sirens sizzle in the sun. When he returns, his mother is swimming with the fishes. Upon Loli's insistence, Leonardo and his brother-in-law go to absurd lengths to conceal his mother's untimely demise. Berlanga's first color film is black in humor and white in sandy-surfaced titillation.
