Nate Stevens is a fairly normal guy…at least on the outside. He lives for his job, working as a medic, caring for patients on board his ambulance. Nate has one good friend, Donny, a cop. He also has a few demons which have haunted him since he was a kid.Hold on tight for a scary ass ride through the gritty streets of Toronto. This one hot call changes the lives of two long time friends, forever. What happens in the aftermath would rock even the most secure of friendships but Nate and Donny’s bond survives. In fact, things seem pretty sweet…that is until one of Toronto’s most notorious crime figures, the Mutt, locks on to Stevens and orders a kill. While one friend searches frantically to catch the rats inside Toronto Police Services, the other is being hunted in the wilds of Algonquin Park. Do the strongest always survive? Or will Darwin’s postulate of Natural Selection hold true?
