In the season premiere of Hawaii Five-0, a terrorist hijacks a drone and puts the entire island in danger. Innocent people are killed and more are threatened, but all their evidence points them to dead ends.

So the team must rely on an unlikely hero to save the day. Who is this savior and how will he or she help the team in a way that no one else can? You'll just have to watch Hawaii Five-0 Season 5 Episode 1 to find out who it is. One thing's for sure, it's probably not the person you are expecting it to be.

But even when the action appears over, there is a lot more to come as new storylines are introduced that will obviously continue throughout the season. Who will the new stories involve? Who's in danger? Who might be getting married? All of these questions and more will be answered when you watch the episode.

If that's not tantalizing enough, how abou this: The episode features Steven and Danny doing something in the first five minutes that we guarantee you never, ever expected them to do. But it's also something that was long overdue.
