As Grace recovers from tragedy, her science class is chosen by Agent Sweeney at the U.S. Fish & Wildlife Service to help with research on the new "Red Wolf Reintroduction Program".
While she’s excited about helping with the conservation of the endangered wolves, Grace knows this means being outdoors in the worst winter on record, in a place she no longer feels comfortable. It also means working closely with Wyn (her ex) and his annoying girlfriend (Skyler), whose only experience with nature is killing two silk plants and watering a cactus.
After wolves show up dead, Grace almost quits. However, when a fellow project team member goes missing, Grace continues the assignment under a renewed suspicion that someone might be sabotaging the conservation program. She quietly begins to hunt for clues.
Little does she know, she is being hunted too.
