Jill McCormick works as the night security guard at an exclusive, high-level conference center on Maryland's Chesapeake Bay. She considers her job a stepping stone to something better in her pursuit of a career in law enforcement, and recognizes that a stint at the prestigious Chesapeake Conference Center will look impressive on her resume. But the tranquil waters turn choppy when the drowning of a prominent guest begins to look more like murder, and the evidence mounts against Jill's boss, the self-centered and unpopular general manager of the center. When the local sheriff seems content to look the other way rather than suspect his good friend the manager, Jill enlists the help of her deputy lover, Mitch Garrett, to conduct an investigation of their own, even though it may implicate both their bosses in the murder.
