That's a wrap on Hawaii Five-0 season 6!

The CBS series finished filming for episode 24 on Wednesday, and the cast quickly took to Twitter to share some behind-the-scenes teasers. From downed airplanes to junkyards to secret military bases, the finale will have it all.

The Internet was bursting with speculation earlier this week when photos of a blindfolded McGarrett (Alex O'Loughlin) surfaced online. While soldiers will escort the Five-0 leader during the episode, it does not look as if Steve will be in any danger. At first blush it looks as if he's in the clutches of a paramilitary organization, but he's really just visiting a military black site, according to writer Matt Wheeler.

Elsewhere, the team will have to deal with a downed plane. Set up on Waikiki Beach since last week, the prop drew plenty of attention on social media.

Grace Park’s Kono will then follow the case to a junkyard where she’ll find herself operating some heavy machinery.
