Dylan Walsh and Jami Gertz are set to star in the Lifetime original movie, Christmas Miracle.

The film is inspired by a true story, centering on the life-or-death ordeal of an estranged Idaho couple, says The Hollywood Reporter. They accidentally get trapped in a blizzard during a snowmobiling trip gone wrong just before Christmas.

Shooting on Christmas Miracle is currently under way in Calgary, Alberta, for a targeted December premiere.
