With season 11 being brought to an earlier expected close, Mac still has unfinished business with Sam and Callen (Chris O’Donnell).
Gemmill confirmed the new to TV Line earlier this year, stating: “Our guys get sucked back in to help Mac,
“And (they) find themselves racing against the clock to prevent Argento (Juan Riedinger), and those secretly working on his behalf, from getting away with murder.”
NCIS: Los Angeles season 12 premieres on CBS in late-2020.
