In The Mafia Boss Happenes to Be My Sex Partner movie, Fiona Shaw's life of luxury shattered when her family's empire collapsed, leaving her burdened with a crushing $500 million debt. To save what's left of her family, she agrees to a cold-hearted bargain: a marriage of convenience to Henry Sterling, the second son of a powerful business dynasty. But behind the glamour of high society lies a painful truth. Henry is gay, deeply in love with his male secretary, Louis, and indifferent to Fiona. He married for one reason alone—to produce an heir under his mother Elizabeth's pressure, secure the family fortune, and defeat his rival half-brother, Jeff. Now, trapped in a loveless marriage and yearning for freedom, Fiona finds herself drawn into a dangerous affair… with a man whose secrets are even deadlier than her own.
