Wealthy-family judge Leonardo suffers from a rare sexual dysfunction caused by childhood trauma, yet unexpectedly has a reaction in front of Elena, an emergency room doctor. To find a “cure,” he signs a secret treatment contract with her, a woman drowning in debt, and their awkward physical contact evolves into a fatal attachment. Meanwhile, the family power struggle intensifies as his cousin and uncle covet the inheritance, and the truth behind his father's death twenty years ago gradually surfaces. Because she grows close to Leonardo, Elena is threatened with kidnapping, and the two face a life-and-death moment at gunpoint. In the end, betrayal and redemption intertwine; this relationship that began as “treatment” becomes armor for exposing the family's sins—and their only place to belong.
