Ciel bleu (1971)

Nicholas is a conscience-stricken international news photographer. Revolted by what he has seen in wars in Africa and Indochina, he leaves his job and his girlfriend to do sports coverage. While covering a rugby match between the French and Irish teams in Ireland, he runs into an ex-American girlfriend, and their affair begins again. As she is very down-to-earth, she helps him begin to sort things out.
