Annie Walker

Annie Walker (Piper Perabo) is a CIA operative with gorgeous girl-next-door looks and the instincts and intelligence of a gifted spy. A brilliant linguist with a thirst for adventure, Annie was plucked from CIA training at the farm to work in the Agency's Domestic Protection Division, where she takes on cases both close to home and across the world. Calm under fire and quick on her feet, Annie quickly proved herself to be a resourceful and effective agent, whether recruiting new assets or facing down ruthless enemies of the state.

Now a full field operative with dozens of missions under her belt, Annie is no longer a rookie-but that doesn't mean she has life as a covert operative for the CIA all figured out. Working for a clandestine agency with endless levels of protocol isn't always easy for Annie, who's better at following her gut than orders. And leading a double life brings its own challenges; though she has finally revealed the truth about her career to her sister Danielle, Annie continues to struggle with balancing personal relationships and her demanding-and often dangerous-job.
