When she awakens from a drugged state, Kate discovers that she is being held by a masked man calling himself Casanova, and she is one of several prisoners trapped in his lair. She manages to escape and is severely injured when she jumps from a cliff into a river. After she recuperates, she joins forces with Cross to track down her captor, whom Cross concludes is a collector, not a killer, unless his victims fail to follow his rules. This means there is time to rescue the other imprisoned women, as long as they remain obedient.
