This drama from executive producers Josh Safran and Mark Gordon explores the lives of young FBI recruits who have come to the Quantico base in Virginia for 21 weeks of training to become special agents. The recruits have been thoroughly vetted and are considered the best and the brightest - but each one possesses secrets, including hidden reasons for enlisting. One recruit is harbouring the biggest secret of all, and he ends up being suspected of masterminding the most deadly attack on U.S. soil since 9/11.
