Jaguar, left on her own, goes off to the home planet with her friend Rachel to watch some Formula One racing in Montreal. There, a lost dog leads her to some of the fastest women on the planet, and when one of them is killed, she's stuck with the dog and the case. In short order she realizes that the man responsible for the death is the same one who made Alex leave, and he won't rest until both she and Alex are dead.
