NCIS: Los Angeles: Season 1, Episode 2

1 - 2: The Only Easy Day

When three Navy SEALs interrupt a drug deal to steal the drug money, a SEAL and an undercover LAPD officer end up dead. NCIS watches the surveillance footage, and Sam Hanna recognizes a former Navy SEAL colleague, and the hunt is on to find the other team members and the evidence needed to convict them. Sam confronts his old friend, but gets little satisfaction. He's personally offended that his former brethren could violate their code so profoundly, particularly when one of their team turns up dead, having been killed in the initial robbery. In a surprise twist, the investigation leads NCIS to discover the undercover cop wasn't there to take down the drug dealers, but another police officer who is leading a double life selling drugs. Using their skills as interrogators as well as their undercover acumen, Sam, G. Callen and the team are able to arrest the SEALs involved, as well as take down the corrupt police officer.
