In this next "NCIS: LA" episode, an undercover agent (Daniel Henney) is suspected of working for the smuggler he should be investigating, so the team takes him into custody to determine his true intentions. Meanwhile, Kensi (Daniela Ruah) and Deeks (Eric Christian Olsen) discuss their personal relationship, something that was questioned in the last episode, as Kensi returns to the field after being kept in Ops in "Windfall."

The "Three Hearts" promo is all about this rogue undercover NCIS agent, as the team – and everyone, including Hetty (Linda Hunt) and Granger (Miguel Ferrer), is involved in this case, as you can see – must figure out if he is an asset or an adversary. Can they trust him? His attitude doesn't help, as he easily gets out of cuffs. "If you're going to cuff me, do it right," he tells them.

Plus, don't forget to check out the slideshow of promotional photos CBS has released from this episode.

"NCIS: Los Angeles" season 5 airs Tuesdays at 9 p.m. on CBS. What do you think of the episode 21 "Three Hearts" photos and promo?
