Sean King and Michelle Maxwell aren't your typical private investigators. Both are former Secret Service agents, and their unique skills - not to mention their razor-sharp chemistry - give them a leg up on conventional law enforcement. Maxwell is a former elite athlete who uses her brains, beauty and Beltway connections to solve cases. King's career in the Secret Service ended when the presidential candidate he was assigned to protect was assassinated, sending him on a downward spiral. Today, King has added a law degree to his arsenal of skills, allowing him to navigate the system in ways a typical private investigator never could. Along the way, King and Maxwell clash over everything, from her garbage-strewn car to his love of wine over beer.
