A shy maths graduate takes a holiday in Dinard before starting his first job. He hopes his sort-of girlfriend will join him, but soon strikes up a friendship with another girl working in town. She in turn introduces him to a further young lady who fancies him. Thus the quiet young lad finds he is having to do some tricky juggling in territory new to him.

In 1995, producer Françoise Etchegaray recorded the production of A Summer's Tale. The footage remained on the shelf for years until director Jean-André Fieschi combined the images with bits of the finished film.
