Antonia (Margherita Buy) and her husband Massimo (Andrea Renzi) have been living a happily married existence for the better part of 10 years when a sudden and tragic accident kills Massimo. Barely able to survive her grief Antonia discovers that her beloved Massimo has been carrying a secret life for a good many years. Shocked out of her grief, Antonia begins to search for details and any information leading to Massimo’s mistress, only to discover that his secret lover is a man, the very handsome, young Michele (Stefano Accorsi). When she slowly begins to meet the rather large extended "family" of friends who spent so much time with Michele and Massimo over the years, Antonia finds herself drawn to her husband’s other life.

HIS SECRET LIFE is the final installment in the erotica trilogy from acclaimed director Ferzan Ozpetek (STEAM: THE TURKISH BATH, HAREM).
