Erica Shepherd (Jennifer Carpenter) is a brilliant former CIA operative, now known as one of the most notorious traitors in recent American history serving life in a Supermax prison. Against every fiber of his being but with nowhere else to turn, FBI Agent Will Keaton (Morris Chestnut) enlists Shepherd to help track down a fiercely dangerous and elusive criminal, known as Tal, whom she knows all too well. While Shepherd and Keaton have different motivations for bringing the enemy to justice, they both know that to catch a spy… they must think like one. Can Shepherd ultimately be trusted? That is also a major question that will be explored over the course of the season. The show also stars Raza Jaffrey, Kelli Garner, Cassandra Freeman, and Noah Mills. The first season of ‘The Enemy Within’ airs Mondays after ‘The Voice’ on NBC. The season finale is set to air April 29.
