We have to go out, but we don't have to come back. When a distress call is received at the Casco Cove Coast Guard Station in Alaska, Rick O'Neill readies his team for a rescue mission. In the storm-tossed freezing waters they find the foundering Russian cargo ship, but when they try to make contact they receive no response. Boarding what appears to be a deserted vessel, O'Neill begins to realise that nothing on this ship is as it seems, and he may have just led his team into a trap.
