Sylvaine is the rightful heir to a New Orleans perfume dynasty until her stepfather murders her mother and seizes the family estate. To stay alive and keep plotting, she fakes madness and spends five years imprisoned in a basement lab, injected with pain-inducing drugs while her stepsister Margaux steals her formulas and builds a glittering reputation on them.
When crime lord Dorian, who depends on calming scents he believes Margaux makes, appears at a yacht gala, Sylvaine plants a family crest to draw him toward the truth. As she sets traps and survives staged accidents, she and Dorian forge an alliance that turns into something deeper, with the men smuggling banned chemicals through her family's shipping routes still holding all the power.
