Plot summary
Uranium is stolen in Moldova. A military raid to halt the sale of the stolen uranium ends badly. Two American girls, who had attempted to join a terrorist group, are taken into custody by Saudi Arabia. Elizabeth, who is hosting a conference on women's education, is instructed not to attend the keynote by a Saudi Arabian woman who had been attacked with acid for speaking out against gender segregation in the workplace, because it might interfere with a pending arms deal with Saudi Arabia. Saudi Arabia returns the girls, and FBI interrogation learns that they were supposed to have been part of an attack on the keynote speaker.
Learning of this, Elizabeth orders the conference shut down. Henry and their children, who attended the conference, evacuate just before a woman forces her way past security into the conference room and blows herself up. The children are taken to the hospital to check for radiation exposure, while Henry goes back in to help the injured.
