Watch Eric Christian Olsen Get All Wet in 'NCIS: LA' [Video]

It looks like NCIS: LA star Eric Christian Olsen is literally getting his feet wet in this week's episode of the popular CBS procedural, "Forest for the Trees." While on the trail of missing team leaders Callen (Chris O'Donnell) and Sam (LL Cool J) — who have been kidnapped after pursuing an anonymous tip about a vanished NSA agent — LAPD/NCIS liaison Marty (Olsen) pays an undercover visit to a possible lead.

"I just came to get some advice about my business," Marty says to his immediately suspicious mark in this exclusive clip. Rather than wait around to dispense said advice, the guy hightails it into a nearby stream, while his pursuer drops the act and whips out his federally-approved sidearm, calling out: "Not in the water, that looks incredibly… cold!" But he ends up putting professional duty above personal comfort, doing a flying tackle to bring his target down and continuing to wrestle with him in the cold, cold water. Meanwhile, his partner Kensi (Daniela Ruah) watches the action from the shore, staying dry while her buddy gets damp all over. Time to start issuing a towel to all NCIS agents, along with a badge and a gun.

NCIS: Los Angeles airs Mondays at 10 p.m. on CBS.
