Off the northeast coast of Russia, the captain and crew of a small crabbing vessel are brutally murdered by members of the Russian Mafia. After the Bratva thugs stuff the dead bodies into crab pots and throw them overboard, they scuttle the vessel off the coast of Alaska and slip ashore.

In Washington DC, Supreme Court Justice Charlotte Morehouse prepares for a trip to Alaska, unaware that a killer is waiting to take his revenge-by livestreaming her death to the world.

In Anchorage, Alaska, Deputy US Marshals Arliss Cutter and Lola Teariki are assigned to security detail at a judicial conference in Fairbanks. Lola is tasked with guarding Justice Townsend's teenaged daughter while Cutter provides counter-surveillance. It's a simple, routine assignment-until the mother and daughter decide to explore the Alaskan wilderness on the famous Glacier Discovery train. Hiding among the tourists, eccentric locals, and other passengers are the Chechen terrorists, who launch a surprise attack when the train reaches a remote area. While they seize control of the engine, Cutter manages to escape with Justice Townsend by jumping off the moving train-and into the unforgiving wilderness.

The chase is on. With no supplies and no connection to the outside world, Cutter and the judge must cross a treacherous terrain and commandeer a raft through an icy river canyon to stay alive. Two of the terrorists are close behind. The others are on the train with the judge's daughter-and they plan to execute her on camera. With so many lives at stake, Cutter knows there are only two options left: catch the train and kill them all . . . or all will be killed.
