When the "Kirkland Lake gals of 1941" begin to share their story with a present-day audience, a siren sounds and they soon find themselves pulled right back into the fateful winter of 1941-42. There, they gather again at the mine-head, waiting for word on the men trapped underground, as their fear and rage builds. When the husband of one of the women is badly injured, their desire to help her quickly leads them into a much larger campaign to help all the families they can. Before long, they've become the heart and soul of a large-scale union-organizing drive that is fuelled by their sheer will--and sometimes giddy enthusiasm--but that is also put to the test by their own inexperience, a bitter strike, and the brutal force of the powers that be.
