While T'Pol is spared, the crew becomes obsessed with trivial tasks as Enterprise studies a black hole in a trinary star system.
Enterprise studies a black hole within a trinary star system, and radiation from it begins to affect the human crew. Everyone becomes fixated on small projects: Archer on a preface to a biography of his father, Tucker on redesigning the captain's chair, Reed on a security alert system and Sato on a new menu.
Phlox becomes obsessed with treating Mayweather's headache, nearly operating on him. T'Pol, who is unaffected, discovers that the radiation is to blame and must guide the ship through the danger with the crew incapacitated. The episode was directed by Patrick Norris and written by Chris Black.
