When mega-heiress Ella Pierce is abducted by an extremist group bent on punishing her industrialist father, the team rushes to find her captors. When Ella's father refuses to negotiate with the kidnappers, now identified as the People's Nationalist Agenda (PNA) the group stages a robbery at one of his factories to keep his attention. Knowing the PNA will strike again, the team correctly determines when and where the attack will come, and a gun fight erupts when they attempt to free Ella. However, instead of fleeing, Ella opens fire on the FBI, and most of the PNA members escape. The team assumes that Ella has Stockholm Syndrome until they are able to hack into her computer, where they discover emails from Ella to the leader of the PNA, urging him to use her to target her father. With the help of Charlie's math, the team locates the PNA's hideout, and they are able to shut them down. In the end, they discover that Ella felt neglected by her father, so she set up the whole situation to get his attention.
