Season 3 of NCIS: Los Angeles hits the ground shooting as the team lands in Romania to rescue their boss and friend, Hetty Lange (Oscar winner Linda Hunt), from a ruthless crime family. But Hetty's mission is as much personal as it is professional, revealing a bombshell secret about team leader "G" Callen's (Chris O'Donnell) past. This secret culminates in the team's first-ever collaboration with Hawaii Five-O, in a joint effort to prevent a global pandemic... which ultimately brings Callen's vendetta full circle. The team pulls together with the bold moves of ex-Navy SEAL Sam Hanna (LL Cool J), Special Agent Kensi Klye (Daniela Ruah) and LAPD liaison Marty Deeks (Eric Christian Olsen). While the operatives hunt the world for criminals, Eric Beale (Barrett Foa) and Nell Jones (Renee Felice Smith) are the home-base tech wizards who keep them posted on all international intel.
