Last night's NCIS: Los Angeles season premiere revolved around an old-school, generations-old feud dating back to World War II, shedding new light on Callen's past and Hetty's complex relationship with her protege.

Next week's adversary is definitely a 21st Century foe.

The team joins forces with the NSA to find the creator and controller of a software program linked to a cyber attack against the Department of Defense, the consequences of which would be immense.
