Anna Espinosa was a cold-hearted assassin - the ruthless and persistent nemesis of Sydney Bristow. In season one, she worked for K-Directorate, a rival organization of SD-6. She was their "go-to" officer for wetwork and active measures. After the "The Man", aka Irina Derevko, took down the organization and seized control of its assets, Anna faked her own death. Afterward, she worked freelance, selling her skills as an assassin to the highest bidder.
