Two of Broadway’s brightest leading men, Tony winners Nathan Lane (The Producers) and Leslie Odom, Jr. (Hamilton), open the curtain on their surprising family trees with the help of Henry Louis Gates, Jr., who surprises Odom with an image of an unexpected ancestor: a white assistant surgeon for the Confederacy. For Lane, this journey into the past is an opportunity to learn about a history that his alcoholic father, who died when Nathan was 11, was never able to share.

Returning with all-new episodes now that the Olympics are history, the franchise kicks off with a storyline involving Oa’s (Zeeko Zaki) Muslim heritage, when he reconnects with his former mosque’s imam who insists a slain Muslim college student and his brother were falsely targeted as terrorists in their double murder. In his investigation, Oa is uneasily paired with a Muslim anti-terrorist agent who’ll do whatever it takes to solve the case. On FBI: International (9/8c), Lost’s Elizabeth Mitchell returns as Angela Cassidy, Forrester’s (Luke Kleintank) estranged mother, an accused traitor who only recently re-entered his life. On FBI: Most Wanted (10/9c), Jess (soon-to-depart Julian McMahon) hopes his newly empty test is the right place to properly woo Sarah (Jen Landon).
