Trama

A picnicking couple encounter a dead body, which proves to be that of a first lieutenant in the US Marine Corps; after Gibbs chats with Dr. Ryan, he and the team investigate; the gang see that the victim had plummeted from somewhere in the sky after he had first been beaten, stabbed, and shot; in one of his pockets they find a challenge coin, which they trace to a woman commander in the Navy Chaplain Corps, who is on duty with a relief team in Colombia. Ducky finds curious clues, and Abby interprets them (connecting to Colombia); Ziva communicates with Monique, a contact in Colombia, who repeats a rumor about the disappearance of the Marine and the chaplain; Ryan gives Gibbs a tip. Tony, Ziva, and a second woman chaplain join Monique in Colombia; someone else provides fireworks; then Gibbs interviews a mule. McGee continues to dig, then Ziva and Monique meet a couple and get answers. Tony, Ziva, and two chaplains fly back home with their new friends.—DocRushing

The body of a Marine first lieutenant (first beaten, stabbed, and shot) falls from the sky; Gibbs and company investigate. Tony and Ziva go to Colombia and, with help from the team, find answers about both the victim and a missing chaplain.—DocRushing

A couple tries for their third picnic spot, but the woman's not happy. She relocates to under a tree. As she does, the spot they just left becomes the landing pad for a body falling from the sky.

Jimmy comes in to work in a trenchcoat and flashes his wedding duds. A powder blue tuxedo with frilly pink shirt. They've decided to go "kitsch". They're all in the wedding, but he hasn't picked a best man yet.

Gibbs calls in with the body of the week. They find his absence suspicious.

At his house, he says good-bye to Samantha (Jaime Lee Curtis). She stayed over. They're all glowy.

At the scene, Gibbs is running late. The victim could have fallen anywhere between 400 and several thousand feet. He's First Lt. Walter Larabee. He looks stabbed or shot in addition to his broken bones from the fall. They find a challenge coin from the chaplain corps in his pocket. It's caked with dried blood.

At the office, Gibbs meets with Navy Commander Maria Castro, a chaplain. She doesn't know Larabee, but knows Navy Commander Theresa Wade, the woman the blood on the coin was traced to.

Chaplain Wade has served multiple missions in Iraq and Afghanistan, about a month ago she went on a relief mission to Cartagena, Colombia. They haven't been able to reach her for a week. Castro is really worried about her.

In the morgue, Duckie pre-emptively rejects the best man honor -- mentors make terrible wingmen. But he's psyched about the tux. Gibbs joins them. "Allow me to make my way from the horrific to the curious," Duckie says.

Larabee was beaten, stabbed and shot. He was alive when he was thrown from the aircraft. There were bullets in his vest and tiny fungi crammed in his taped shut mouth.

Time for the victim rundown. Larabee was 32 and just finished his second tour in Afghanistan. He just accepted a tour to the embassy in Colombia. His wife is pregnant with their first child.

There were three planes in the airspace over the park when Larabee was dropped: a medical transport chopper, retired air force pilot and his family and a single engine Cessna registered to Alfred Holbrook, who was busted 30 years for possession with intent to sell.

Tony and McGee inspect Holbrook's plane. He's been in a wheelchair for a year and two months since getting hit by a drunk driver. He suggests his license was stolen and his plane hasn't left the ground.

Down in the lab, Abby reports the bullets came from a Russian AK 47. The mushroom is an herbicide for cocoa plants, used only in Noreno, Colombia. Cartel country.

Upstairs, Palmer asks Ziva for advice on who to pick as his best man. She tells him to go with his gut. Ziva is waiting for a call and it comes through in MTAC. Ziva talks to her old friend Monique, who says she might know how to find Wade.

Monique is working on a school construction project. She heard the cartel is taking Americans. She's Retired Interpol Agent Monique Lisson. She has footage from the Cartagena police showing chaplain Wade and Larabee getting into a Courage Mission International van. They provide vaccines and antibiotics to villagers.

Gibbs suggests Ziva join Lisson in Colombia.

Ziva says Lisson is like a sister. She doesn't want Tony going with her, but Gibbs insists. Castro insists on going as well.

Gibbs runs into Samantha in the elevator. She says DOD knows he's on top of it. She gives him a pizza box. Inside says: "Carter's Nursery, Fairfax. See Manny."

In Colombia, Ziva, Tony and Maria check in to their hotel -- they're stuck sharing a room. Monique meets them and says they have to wait until dark to travel to the village.

McGee pays Manny a visit at the nursery. He flashes his badge and Manny runs. Gibbs stops him with a trash can lid. Manny is a drug smuggler set up by the government after flipping. He says a drug run from Cartegena would be $50,000.

Then he says he's doing flights for the CIA. He flew down empty and flew back with medical canister filled with vials of blood. But he says he can prove he didn't fly yesterday.

In Colombia, Monique tells Ziva stories at a sidewalk restaurant. They are interrupted by a drive by shooter. They take cover and are unharmed.

They talk to Gibbs in MTAC, Monique insists she wasn't followed. Tony is suspicious of her.

Later at night, Tony talks to Maria. He asks her why she insisted on coming with them. Chaplain Wade's assignment to bring immunizations to the local villagers was supposed to be hers. She feels responsible.

Back in NCIS, McGee confirms Manny the mule's alibi on a school trip with his son. Gibbs wonders why Samantha gave him his name.

Gibbs pays her a visit, saying her tip got them nowhere. She swears she didn't know about Colombia until he got involved. She says she can't help it, she hears things and starts digging. She thinks it's possible Wade and Larabee stumbled on to something. She suggests he bring his team home. She says she doesn't know what happened to the missionaries they were traveling with.

McGee called their number and got a recording.

Gibbs wants answers. McGee runs two names from Wade's emails: Stephen Wheeler and Constance Mazney. He runs them and finds they both have blocked government files.

Palmer visits Abby in the lab and asks her to be his Best Woman. She's thrilled.

Gibbs joins them. The AK 47 that killed Larabee is the weapon of choice of the Lazaro cartel which operates where the missionaries were heading with vaccines.

Monique and Ziva talk a walk. Monique confesses she's involved with something she can't get out of and she wants to protect Ziva. She tells Ziva to go home and accept they can't solve the case. Monique warns her she could end up dead if she doesn't.

In the office, McGee breaks through the files on Wheeler and Mazney, the people who guided Larabee and Wade into the mountains. They're not missionaries; they're CIA.

Gibbs takes their names to Samantha, who says the vaccinations are a ruse to take blood samples of the cartel to connect the families by DNA. There really are vaccines, but Wade and Larabee didn't know what they were up to.

Gibbs tells her to just tell him up front next time.

Ziva tells Monique about the CIA. She says she doesn't know any more than that.

Tony and Ziva resolve to find the CIA.

Two people race into their van, on the run. Ziva and Monique pop out of the back. The CIA people say the chaplains were there as cover. The cartel made an example out of Larabee. They assume Wade is dead, but Ziva isn't ready to give up. "What do you guys have in mind?" Mazney asks. "Bang," says Ziva.

Cut to news footage of a cartel warehouse fire in Cartagena. They video conference with Tony and Ziva in a van -- they have Wade and are on their way to the airfield with Monique.

At the airfield, Monique says she's staying behind. She still won't tell Ziva what she's up to.

Gibbs answers his front door. He invites Samantha in for a beer. He's still a little bitter she kept things from him. Samantha says Lisson has information she needs and has screwed her over the years. Samantha knew Lisson was involved from day one.

He asks her if she's staying. She doesn't have a sitter. They cuddle on the couch.
