The "NCIS: Los Angeles" team is going on "Red" alert.

Tuesday night's installment of the hit CBS crime drama will serve as the pilot episode for a new spinoff, "NCIS: Red," starring John Corbett.

Now in its fourth season, "NCIS: Los Angeles" is itself a spinoff of the original "NCIS" series, which first debuted on CBS in 2003.

"NCIS: Red" is set apart from its predecessors by its constantly-changing setting. Corbett stars as a retired agent who returns as an analyst helping out the special "NCIS Red" mobile unit which investigates crimes around the country. The first episode of the new series takes place in Idaho.

"They get to work and live together. And that hasn't been done before on either of the two NCISes," said Shane Brennan, the executive producer of all three "NCIS" series.

Former "Grey's Anatomy" cast member Kim Raver stars in the spinoff as the team's ambitious leader, Paris Summerskill.

"She's supersmart, supercapable," Raver said of her character.
