Montreal, 1975. Detective mile Cinq-Mars is transferring from the Night Patrol - the notoriously tough department of officers in charge of watching over the city as it sleeps - to the day shift. His old superior has seen to it that he's assigned to partner Yves Giroux, another ex-Night Patrol detective some say isn't on the 'up and up'.

Getting in a house is easy for thief Quinn Tanner. The stress comes in getting out clean. On finding her getaway driver dead after her latest heist, she goes underground.

For his first case on the day shift, mile is sent to the property that Quinn has just visited, and their paths are set to cross. But has she stolen something more valuable than she realizes . . . and who is hunting for her now?
