The presidential race clarifies on the day of the Iowa caucuses, as does Josh's relationship with Amy Gardner (Mary-Louise Parker). Meanwhile, Josh must make a call he'd rather not make to an old friend who's protesting Navy arms testing at Vieques, Puerto Rico; Toby and C.J. disagree about affirmative action; Donna tries to get out of jury duty; and Sam meets with a ufologist (Sam Lloyd) who tells him that most of the gold at Fort Knox has been replaced with something else.
