A rare revisiting of an old storyline on NCIS: Los Angeles. Not as good as the original concept involving Sam, but it was still a step-up from the previous two weeks. When they focus ona serious issue the show is so much better. Unfortunately, it was not all serious as you still had that techies having their usual unamusing banter. Not necessary at all.
I'll give this episode a good score, but there is still room for improvement.
