Detective Ronan Lee has just solved the crime of the century, or has she? The case of the copycat killer plunges her into an ancient mystery, but solving the murders raises questions about the world government's true objectives. An unexpected invention gives her the chance to travel to the past. Her target is the 21st century and her mission is to save the woman at the heart of issue. This same woman, Sidney Williams, is a warm, personable and accomplished actress that Ronan would give her life to protect.
Unaware of what fate has in store, Sidney's life is boringly predictable until a mysterious stranger comes out of the darkness of night to protect her. She knows there's something unusual about Ronan, but despite her misgivings, she can't deny the mutual attraction. All of this takes a backseat when she's plunged into a harrowing game of cat and mouse that could destroy everything she holds dear.
