Hawaii Five-0 will conclude its third season on Monday, May 20 on CBS. If you want to know the major happenings abound on the cop drama's final hour, here are the spoilers revealed by TV Guide:
The team must find a terrorist who landed his hijacked transport plane in Oahu before he is able to carry out his attack. All the while, Kono is on the run for a murder she didn't commit and McGarrett learns some shocking news from Wo Fat. Could it have something to do with what happened between Wo Fat and McGarrett's mother Doris in the safe house? And can McGarrett trust either of them? "We find our team risking it all by putting their trust in people or things that maybe they shouldn't," executive producer Peter Lenkov says. "We'll see if their faith pays off." As for whether Doris will stick around, Lenkov says, "We've only just begun to scratch the surface on Doris McGarrett. … Her story's not quite done yet." But someone will likely say goodbye. "The English translation of our finale title is 'Farewell and take care,' Lenkov says. "You can take want you want from that."
An all new Hawaii Five-0 airs next Monday with S03E21 titled "Imi loko ka 'uhane". Watch an extended promo released by CBS below:
