FBI

CBS | 9:00 pm

After Valerie Caldwell (guest star Sasha Alexander), a front runner in the presidential race, is targeted by a car bomb, OA and Maggie (Zeeko Zaki, Missy Peregrym) race against the clock to find and stop the would-be assassin before he or she strikes again in a new episode called "American Idol." As they investigate, however, the duo starts to wonder whether Caldwell's assailant might be motivated by something other than politics. Fernando Funan Chien also guest stars; Alana De La Garza also stars.
