James (Colin Farrell) successfully passed the initial review of the CIA as an honor student, and entered the training base with other elite students to receive special training. The CIA sent the most experienced ace agent Walter (Al Pacino) to train this group of young people. In the almost cold-blooded and cruel training, James, who performed the best, was inexplicably eliminated. Among the newcomers, female student Leila (Bridget Moynahan) aroused the suspicion of the upper level. It was suspected that she was an undercover sent by a hostile intelligence organization. Therefore, James, who had a good relationship with Leila during training, was quietly arranged to work against undercover. James began to deliberately approach Leila to inquire about the situation. But as the two got along, he actually had feelings for Leila, who didn't know whether he was an enemy or a friend. In the face of national honor and personal emotions, how should James's distressed heart choose?
