When he?s lost in the woods looking for his dog as a blizzard blows in, a despondent city-dweller must find a way back to his remote cabin before he freezes to death.

I am curious about the off screen backstory.? What's a city dude doing in a remote cabin?? Is there a deeper cause to his despondency than the loss of his dog?? Is his walking around lost in the blizzard a metaphor for how he is lost in a blizzard of loss and failure in his life in general?? Will there be flashbacks to how he got lost in his personal life, ended up in the remote cabin?

Oh, and could the he be a she?

I see a man in a snow storm stumbling from tree to tree looking for shelter. Maybe the storm is blinding and even the trees are hard to make out. Soon it will be dark and in a snow storm, the darkness is total. Without shelter, your MC will die within hours, so your film is almost real time.

Is this your intention?
