After seven years of a secret marriage, military battlefield surgeon Audrey helped her husband Alexander become CEO of a medical group—only to be betrayed by his affair. After divorcing him, she returns to the military to investigate her father’s death and the takeover of her family’s pharmaceutical company. Alexander’s use of an incomplete formula triggers a medical disaster and collapses the group; his mistress turns over evidence, and he is imprisoned. Audrey treats the victims and begins a new life with Lucas, who has always protected her.
