Some trails never end and some shadows never stay buried.
Deputy U.S. Marshal Murphy rides into the teeth of a killing winter storm with a dangerous prisoner handcuffed to his saddle. When the blizzard strikes full force, he takes shelter in a remote line shack — only to find a young widow and her two small children already fighting to survive inside.
Before the night is out, the prisoner’s gang tracks them down. Trapped by howling wind and drifting snow, Murphy, the widow, and the children face a desperate siege against hard men who will stop at nothing.
