Set in Tumbler Ridge, British Columbia, Grace and Sugar Ducharme are infamous twins marked by tragic events from their past: their triplet died in the birth canal, and on their twentieth birthday their mother was killed while their father was split in half by lightening. As if this wasn't bad enough, each year on their birthday Grace finds a dead body. But this birthday will be different - it's lucky thirty! Unfortunately for the sisters, a serial killer with a fancy for strippers is on the loose... In the midst of their birthday celebration, a nomadic cop killer, Trout Stanley, wanders into their house. Just like the Ducharme sisters, Trout has major 'sibling issues' - his unborn twin brother is trapped inside his body.
