Crack CIA agent Carrie Mathison plays by her own rules when it comes to protecting the US from terrorist attacks. Her uncanny intuition, dogged determination, and gift for persuasion have helped her convert allies, thwart plots, and take out terrorists, often using controversial methods that are uniquely her own. But Carrie's particular mix of traits also includes bipolar disorder, for which she must take daily medication in order to function. Her unusual sensitivities make it difficult for her to maintain the line between her personal and professional lives. She readily tries to get emotionally close to her targets and is not even above using sex to get what she wants, but the results often wreak havoc on her personally.
