Ep 19. Hand-to-Hand

NCIS: Los Angeles season 1 episode 19, titled "Hand-to-Hand," sees the team dealing with a complicated case involving a group of Marines who have gone missing while on shore leave in Los Angeles. The team is brought in to investigate the disappearance of Sgt. Andrew Weaver and his girlfriend, who were last seen leaving a nightclub in the early hours of the morning.

As the investigation progresses, the team discovers that the missing Marines were involved in an underground fighting ring. This leads them to a former Marine named Brice, who runs the ring and has a grudge against NCIS for investigating him in the past.

Brice proves to be a formidable opponent, and the team realizes that they will have to fight their way through his organization in order to find the missing Marines. With the help of martial arts expert Sam Hanna, the team engages in a series of hand-to-hand combat battles against Brice's fighters.

Meanwhile, Special Agent Callen finds himself forming a relationship with an informant who has ties to Brice's organization. This puts him in a difficult position, as he must balance his feelings for the informant with his duty to bring down the fighting ring.

As the team gets closer to uncovering the truth behind the disappearance of the Marines, they must use all of their skills and resources to stay one step ahead of Brice and his organization. With each new fight and each new clue, the stakes become higher and the danger more intense.

In the end, the team is able to track down the missing Marines and bring Brice and his organization to justice. But the experience has left them shaken, reminding them of the sacrifices that they make every day in order to keep their country safe.
