This film makes fun of the Catholic-Protestant divide in Northern Ireland. It seems that the Protestant majority feels threatened by the prospect of a rising Catholic population. The plot develops when a young Catholic man finds that he is extremely fertile now when most men are experiencing a decline in sperm count. At first he is considered a hero, providing the necessary means for many infertile couples. However, things get rough when some think he should only serve Catholic couples and not Protestant.
The ability to enlighten and entertain at the same time is wonderfully achieved in this film. Nether side is shown as villains. Both have the same needs and wants: love, family, alcohol.
