In light of the Operation Manager's sudden departure—and amidst a dangerous nuclear threat—Executive Assistant Director Shay Mosley (Nia Long) arrives on the scene to oversee the LA team and promptly begins making staffing changes.

Meanwhile, Sam (LL COOL J) continues to mourn the loss of his wife, which we saw in the last two episodes of Season 8 (the full episodes, "Uncaged" and "Unleashed," are available to stream on CBS All Access). As a result, he tries to convince Callen (Chris O'Donnell) to find a new partner in the new episode entitled "Party Crashers."
