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.
After a major Tal operative escapes CIA custody, Shepherd returns to Langley to help track the fugitive down. Shepherd and Keaton discover the CIA is withholding vital information on Tal, so they spy on the CIA to find out what the agency knows.
