Burt Lancaster stars as the titular merchant in this classic adaptation of Pope John Paul II's best-selling play "The Jeweller's Shop," an inspiring drama about three married couples and their ups and downs in holy matrimony. With a faithful jeweler acting as their spiritual adviser, three sets of husbands and wives struggle to live their lives with love, steering clear of avarice and infidelity. Olivia Hussey and Ben Cross also star.
