Right before the Christmas holidays, Detective Maggie Doyle and her prosecutor husband, Ian, put away a major drug kingpin in a Manhattan court room. When the kingpin vows revenge while behind bars-and he has the connections outside to stalk and kill Maggie and Ian-their annual Christmas get away to a rustic Vermont cabin isn't the peaceful one they'd hoped it would be.

Maggie relives the takedown that involved Allia, her canine, and Brian, her rookie partner, who was shot during the melee. While Brian is recovering, Maggie deals with the guilt that she failed to protect him. But when Maggie and Ian's Manhattan friends arrive as their holiday guests, Maggie tries to forget that chaotic day. However, the kingpin's threat continues to echo in her head. Now she has four people, including herself, to protect.

While surrounded by Ian, Allia, and her friends, Maggie manages to get back into the holiday spirit… that is until while walking Allia outside, just before a snowstorm, Maggie falls into a snowy trap.

Injured, Maggie looks up from a hole she'd fallen into, only to see the drug kingpin's henchmen staring down at her.

They got her!

Knowing, Ian, and her guests are in danger, her only hope is that Allia could run back to the cabin and summon for help before it's too late.
