NCIS: Los Angeles Season 4 Episodes

24 Episodes 2012 - 2013

The crime drama's fourth season picks up where Season 3 ended with Callen (Chris O'Donnell) facing the fallout for shooting his archenemy, the Chameleon (Christopher Lambert). He is immediately suspended while the case is investigated, but that's the least of his problems when Iranian hit men kidnap and torture him to obtain information on an Iranian double agent. Meanwhile, Hetty (Linda Hunt) adjusts to retired life, but her time off is short lived. As for Sam (LL Cool J), he helps an Afghan elder, who assisted him years before when he was wounded on a mission, search for the man's missing nephew; and he worries about the safety of his wife Michelle (Aunjanue Ellis) when she is called to resume her former CIA cover as an assassin for international arms dealer Isaak Sidorov (Timothy V. Murphy). Later, Callen and Sam fly to Idaho and join forces with NCIS: Red, a mobile team of agents led by special agent Paris Summerskill (Kim Raver), when a murder weapon found there matches one used in a national-security case in Los Angeles. And just as partners Kensi (Daniela Ruah) and Deeks (Eric Christian Olsen) grow emotionally closer, Hetty shakes up the teams and pairs Kensi with Callen and Deeks with Sam to search for stolen nuclear weapons.
