In a galaxy far away, alien criminals organize a spectacular prison break. Pursued by their home planet's authorities, their leader Zin decides there's only one place to go: through a wormhole that allows instantaneous travel to Earth. Cole is the Alien Tracker who's in hot pursuit of the escaped convicts.

Criminal organizations succeed by enforcing a strict code of trust and loyalty. To penetrate these organizations and gain access to their inner circles the police need a magic bullet. Alex Caine is that magic bullet. Only thirty years old, Alex, who grew up hard on the mean streets of Montreal, already brings a lifetime’s worth of experience (foster care, military service, prison time) to the world’s most dangerous occupation: professional gang infiltrator. It is his job to befriend criminals, participate in their illegal activities, gather evidence – then live long enough to testify against them in court.
