New details have surfaced on the CBS hit show NCIS: Los Angeles, which will be launching its 22nd episode of its fourth season next week.

The upcoming installment, titled Ravens & the Swans, will reportedly be featuring the return of an old agent, whose presence could serve to form a wedge between the entire team, according to Hollywood Hills.

The upcoming installment will have Callen (Chris O'Donnell) and the NCIS Los Angeles team finding out that a missing persons case handed out by Hetty (Linda Hunt) actually involves an undercover agent from her past, played by former Rescue Me actress Andrea Roth.

Judging by the photos posted, it appears as though the investigation team will be hard at work on the case.

In the previous episode, Callen and Sam's (LL Cool J) basketball game plans were interrupted when the former's babysitter cancels on him at the last minute.

Also, Kensi (Daniela Ruah) made the trek to Tijuana with Marty in order to locate a missing body that was stolen, following the special task force's takedown of a high profile cartel boss.

NCIS: Los Angeles will be air its newest episode on Tuesday, April 30 at 9/8c on the CBS network. Keep checking back for more of the latest info on the TV crime series.
