Marlen and Hilda Jorgensen's family has received two significant pieces of news: one, Marlen has been diagnosed with a terminal illness. Two, a cosmic blast is set to render humanity extinct within a matter of months. It seems the coming Christmas on their Saskatchewan farm could be their last.

Preparing for the inevitable, they navigate the time they have left together. Marlen and Hilda have channeled their energy into improbably prophetic works of art. Hilda's elderly father receives a longed-for visitor from his past. Hilda's teenaged nephew goes missing, and his mother refuses to believe the world is ending. All the while, Hilda's daughter struggles to find her way home from Berlin with the help of an oddly familiar stranger. For everyone, there's an unsettling feeling that this unprecedented reality is something they remember.

As the planet holds its collective breath to see what happens next amid chaos, denial, acceptance, and hope, this one family determines to live every moment as if it's their last. Because, well, it just might be.
