Plot summary
Scorpion has to survive subzero temperatures trekking to the remote McMurdo Station in Antarctica to save a U.S. Special Forces unit in Darfur that is trying to take down a genocidal warlord eviscerating border-town farming villages. The Pentagon lost contact with a low geosynchronous orbit satellite that controls a military drone used to support their operation and the team needs to reconnect it to give cover to the four-man strike team. During the mission, Toby risks his life to save Happy after she gets cut off from the rest of the team by getting lost in a whiteout blizzard.
For her New Year's resolution, Happy starts reading Toby's rival Quincy Berkstead's book, Your Essential Strategies for Saying Yes to Life to be a little more positive and a little less mean and sarcastic, while Walter tries to be more social and Cabe gives up coffee to lower his blood pressure.
