By the terms of her late father's will, spoiled London heiress Epifania Ognissanti di Parerga, the richest woman in the world, cannot marry unless her prospective husband is able to turn £500 into £15,000 within a three-month period.
Contemplating suicide, Epifania melodramatically plunges into the Thames, and when Dr. Ahmed el Kabir, a self-effacing, selfless Indian physician who runs an inadequately equipped clinic for the poor, ignores her plight and paddles past in his rowboat, she swims to shore and accuses him of being an assassin.
Julius Sagamore, the shrewd family solicitor, then suggests that Epifania undergo therapy with noted society psychiatrist Adrian Bland.
Attempting to ensnare him, Epifania feigns injury; the dedicated doctor remains impervious to her charms, indifferent to her wealth, even as they experience a definite 'connection' when he takes her wrist.
Intimidated by the headstrong heiress, Kabir manufactures a deathbed promise that he made to his mother, pledging that he would not marry unless his prospective bride can take 35 shillings and earn her own living for three months.
After Kabir becomes drunk at a scientific dinner hosted by a wealthy doctor, he finds a sympathetic ear in his former professor and mentor, who offers to accept his money.
Deciding to turn her back on the world of men, she announces that she plans to fire her board of directors, disband her empire and retire to a Tibetan monastery once she has evicted all the monks.
