NCIS: Los Angeles is back for a sixth season this June and the action returns in an intensely thrilling premiere to reveal the fates of the NCIS team.

At the end of the last season, special agents ‘G’ Callen (Chris O’Donnell) and Sam Hanna (LL Cool J) are left trapped in a drug cartel submarine that was packed with the explosive substance ammonium nitrate – and the series returns right back to cliffhanger.
