S10E22 finale
Erica Shepherd was one of the CIA's most brilliant operatives until she became one of the greatest traitors in American history, serving a life sentence in a Supermax prison. Now, to save her daughter, she must team up with FBI agent Will Keaton -- a man whose life she destroyed -- to track down a fiercely dangerous, elusive criminal and his legion of spies. While working with Shepherd goes against every fiber of his being, Keaton knows that sometimes to catch a spy, you must trust one.
Flashbacks to the past reveal the fateful events that led CIA Deputy Director Erica Shepherd to betray her country and the ensuing investigation that put her on a collision course with Will Keaton.
