Bugs that can affect the thoughts of people are loose in the arctic. A group of university researchers find themselves in grave danger from these things. One, played by Robert Sean Leonard (the long suffering oncologist on "House") carries around intense guilt from childhood, when he was chosen over his brother by a friend as the two fall through the ice during a pond hockey game. He as been blaming the friend who saved him for allowing him to live. So who should show up but his "enemy," seemingly from the university, investigating the stresses going on there. Well, several of their colleagues are killed through a prevailing madness. It would seem that the danger from the alien insects would be enough to occupy their time, but instead we get this maudlin, whiny banter from Leonard character. His former friend is at least coping. I think the direction and evolution of this episode is laughable.
