"Bigger story, bigger monsters, bigger effects."

That's the promise Logan Lerman made to us about "Percy Jackson: Sea of Monsters," the follow-up to 2010's YA riff on Greek mythology. One look at the trailer we debuted last spring made clear Logan wasn't messing around.

A brand-new exclusive clip, however, shows off the quieter side of "Sea of Monsters" — though it's a side with stakes just as big. In the fresh footage, Camp Half-Blood — the training area where Lerman's Percy and his friends are holed up after the events of the first film — is under attack, and the demigod Annabeth Chase (Alexandra Daddario) and her half-human, half-goat satyr pal Grover (Brandon T. Jackson) have a plan to keep everyone safe. But the camp's head honcho, Dionysus, (a scene-stealing Stanley Tucci) isn't so keen on the idea.

"If you could just listen to me for one moment," Annabeth says.

"I am listening — you want to go on a quest," Dionysus replies. "Oh, it must be Thursday."

The quest she wants to go on is the one that propels "Sea of Monsters" forward — and the one that brings Percy and his friends face-to-face with those enormous monsters: they need to find the mythical Golden Fleece, which can heal anything, including the barrier that protects Half-Blood from attack.

Sipping his wine (as gods of wine are wont to do), Dionysus explains why this is not a smart plan — namely because of the prospect of near-certain death as one enters the Sea of Monsters, known to humans as the Bermuda Triangle.

"[I]t's a risk I'm willing to take for the good of the camp," Grover says.

Dionysus responds, "It's a terrible idea."

Perhaps. But that doesn't mean they won't give it a try.

"Percy Jackson: Sea of Monsters" hits theaters on August 7.
