Elijah Cameron, the son of runaway slaves, has spent his whole life in the British army proving that a black man can be as good a soldier as a white man. After a victory over the French, Elijah promises one of his dying men that he will deliver a scavenged ruby necklace to his wife, Rose, a woman Elijah has admired for years.
Elijah feels bound to protect her and knows a widow with a fortune in jewels will be a target. Rose dreams of using the necklace to return to England, but after a violent attack, she realizes that she needs Elijah's help to make the journey safely.
Her appreciation for Elijah's strength and integrity soon turns into love, but he doubts she could want a life with him, knowing the challenges they'd face. As their relationship grows, she must convince Elijah that she wants him as more than a bodyguard. And she must prove that their love can overcome all obstacles, no matter the color of their skin.
