Dr. "Sport" Warrick witnesses the murder of a family friend who gives her a mysterious black case and instructs her to give it to CIA agent Sean McGee. She escapes into Sean's protective custody and presents him with the case. When a plot by Russia to infiltrate our nation is uncovered, Sean finds out too late how near the enemy is. The dilemma is how to keep Sport safe and resolve the escalating danger to the USA. When they realize the President is the next target, they join forces with a rag-tag team of patriots to stop the assassination.

A strong single woman with a thriving career as a physician, Sport calls all the shots. She has no ties other than three cats and an immigrant mother who desperately wants her to get married. Sean McGee, an agent for the CIA, has sworn to protect his country from foreign invasion, and he is serious about his job. Sean is Caucasian and Sport is African-Japanese. They are both fiercely American. With spies, agents, and local police turning up at every corner, the last thing on either of their minds is romance.

The scene unfolds at a swift pace as Sean and Sport struggle with internal and external conflict. They bicker, yet love continues to grow in spite of their differences. With murder, romance, humor, and intense action at every turn they learn to depend on each other.
