The fourth season of NCIS: Los Angeles starts tonight on M-Net

NCIS: Los Angeles is a drama about the high-stakes world of a division of the NCIS that is charged with apprehending dangerous and elusive criminals that pose a threat to the nation’s security.

By assuming false identities and utilising the most advanced technology, this team of highly trained agents goes deep undercover, putting their lives on the line in the field to bring down their targets.

In the first episode: After Callen’s public shooting of the Chameleon on last season’s finale cliffhanger, all is not well with the team and Callen is suspended.

Meanwhile, Hetty adjusts to retired life.
