作为"海军罪案调查处"的衍生剧，"海军罪案调查处: 洛杉矶"如今已独当一面。 刺激的爆炸场面，明与暗的较量是该剧的主要基调。角色之间相亲相爱充满笑料的对话也为剧情增添了一抹亮彩，甚至已超越剧情成了观众们最为津津乐道的部分。
G, Kensi, and the office crew continue to pursue the wrongdoers and the two missing nuclear bombs while Sam and Deeks remain in custody and endure torture; G and Janvier promote a business deal; Kensi and Granger use an unorthodox technique to obtain some data, then they find Sam and Deeks and use them as bait; Michelle opens fire on both Sam and Deeks, who receive medical attention. Janvier goes outside the plan, and he makes himself untraceable; Sam and Deeks hold an intense chat; Michelle borrows a telephone and finds herself in trouble; Eric starts counting chartered aircraft; the fearless foursome gather on a helipad, where they meet Michelle and two bad guys and hold a shootout. G and Granger find three dead bodies, a live one, and Janvier. A NEST team finds the bombs aboard a ship and seize them; the foursome chat at the office. Four months later in a federal prison Janvier tells G that the game has still not yet ended.
