The Lightman Group are called in when Washington DC comes under terrorist threat. With national security at stake, Cal and co need to be on their A-game.

Jack and the team investigate the disappearance of a 12-year-old autistic boy who ran away during a class trip to a museum. His father, Daniel Norville, chaperoned the outing and Jack is suspicious of Daniel, who was seen yelling at the boy before he went missing. Vivian also wonders why the child's school aide called in sick and can't be located, and Danny suspects a security guard who has a criminal record.
