After an agonizing divorce, FBI agent Jennifer Cooper is ready to move on with her life, and focus on her job, friends, and family. But a spontaneous night of passion with a tall, dark stranger at a career conference changes her attitude. Jennifer finds herself wanting more but reluctant to reach out to her mystery man. After two years, she ends up working as his partner. Much to her horror, she's still as attracted to him as ever -- and he shares her feelings. But more complex and terrifying than their desire for each other is the devious, perverse killer they've been assigned to hunt down. And the killer's next target? It's Jennifer herself.
