The Mcmullen brothers, Patrick, Jack and Barry, come from Irish Catholic families, so once they get married, they can't get divorced. Patrick, young and old, is now engaged to a Jewish girl, but he is not sure it is the best choice, because his mother gave the three brothers a piece of advice before she went back to Ireland to find her true love after her father's funeral. Don't make the same mistake. The married boss, Jack, gives people the impression that the family is happy, but there is an affair. In view of this, the second Barry was determined not to make any promise of love, but fate played a joke on him and let him meet a beautiful woman who made his heart shake and could only be obtained through marriage. The three brothers met in their hometown on long Island to discuss what is true love and the basic values of the family.
