NCIS: Los Angeles‘ G. Callen and Sam Hanna (played by Chris O’Donnell and LL Cool J) will say “aloha” to Hawaii Five-0 — and then Steve McGarrett and Danny Williams (Alex O’Loughlin and Scott Caan) will return the favor — as part of a two-night crossover event for the CBS dramas, slated for May sweeps.
To kick things off, Five-0 showrunner Peter Lenkov says, “Chris and LL are going to come to Hawaii” — where it is revealed that Sam and McGarrett already know each other, having both been Navy SEALs. “There’s a bit of a history there,” Lenkov hints.
When the NCIS agents get wrapped up in what Lenkov calls a “really cool, big stakes” Five-0 case involving a biological weapon, “It ends up taking us to Los Angeles,” with Night 2 of the event unspooling on the Tuesday procedural.
“McGarrett and Danny end up in Los Angeles on our turf, on our terms,” NCIS: LA boss Shane Brennan tells TVLine, touting a “high octane” climax. But lest fans of one show or the either worry about missing half the action, Brennan notes, “You don’t have to watch both to love what’s going to happen.”

Given that NCIS: LA‘s Daniela Ruah crossed her Kensi Blye over to Five-0 earlier this TV season, Lenkov says, “It just seemed like a natural to continue the relationship.”
