Extinction

A zombie movie with the heady aroma of back-bacon.

Yes.  A Canadian Zombie Movie.

These are sprinter types.  With 3 survivors.  Two men and 9 year old girl that has only known a world of zombies.  And the men, former friends, are no longer on speaking terms.

Also:  Nuclear Winter.  It seems.  Or maybe it's just Canada and the winter seems to take forever.  You'd think deep cold would help keep the zeds at bay with very few victims to munch on for 9 years running.  You'd think that, but you'd be wrong.
