Deer Hunters
In post-apocalyptic Canada, guns don't kill people - slapshots do.
For the mutated tribes trying to survive nuclear winter - which is like normal Canadian winter, just more radioactive - hockey serves as a form of ritual warfare in which communities gamble their resources on the abilities of their squad to score goals and bust heads on the ice.
The unwritten code of the post-apocalypse is broken when the Red Deer steal the Atomics' megapotato. Chaos reigns as the Atomics embark on a deer hunt to regain their starchy prize and, just maybe, quell the growing dissent about hockey being the solution to all problems.
