FOX已续订《沉睡谷》第三季。

　　Almost a year has passed since Ellen Parsons left Hewes and Associates. She is now working in the District Attorney's office and is dealing with a fairly important drug case, trying to get a dealer to reveal the identity of his supplier. Patty Hewes is now acting on behalf of a group of investors trying to recover money they had entrusted to Louis Tobin and who, it turns out, was running a Ponzi scheme. With billions of dollars unaccounted for, Patty is trying to find any funds that may have been hidden by the Tobin family. Patty and Ellen have had no contact since her departure but Patty has been reluctant to re-assign her office, convinced that Ellen will return. She even sends her an expensive handbag. Ellen wants nothing to do with her however and when she thinks Patty may be interfering with her drug case, tells her she doesn't need any help. She also tells her that any secrets she may have are perfectly safe. In a flash-forward 6 months into the future, Patty Hewes is in a serious accident when another car broadsides her vehicle in an intersection. The occupant of the other vehicle has fled but it is registered to someone she knows.

　　在Gibbs失踪这两个月里，Bishop临时担任海军罪案调查处的领导。他们试图让一切保持正常，但那几乎不可能。与此同时，巴拉圭任务无论结局如何，都将对本季后续剧情产生持续影响。Jennifer Esposito已经退出该剧，剧情安排她「离开海军罪案调查处去照顾患病的母亲」。这是在荧屏之外发生的，只有台词的描述，没有实际镜头。Maria Bello从15×04开始扮演一名犯罪心理学家，她曾在军中担任少尉，两次前往阿富汗前线。她是少数敢直接挑战Gibbs的人，但她和Gibbs一直都保持着相互尊重，他们的关系很特别。Delilah会在圣诞前后的新集中生下她和McGee的孩子，但也有说孩子在10月的新集中出生。Ducky（David McCallum）有机会在自己的母校致词，但他遇到了一个「非常有影响力的女人」。Clayton Reeves一个「天大的秘密」将在本季开播数集之后曝光，那是一个非常私人化的秘密。Robert Wagner本季某个时刻再次扮演Tony DiNozzo Sr.，Laura San Giacomo再次扮演Grace Confalone。
