Last night we got our first look at the new trailer for Jurassic World: Fallen Kingdom, starring Chris Pratt and Bryce Dallas Howard, and featuring the return of Jeff Goldblum as Dr. Ian Malcom. Today we are getting two more juicy bits from the film. First, we are getting a new synopsis which teases at a larger conspiracy behind the action in the film. Secondly, we are getting some reassurance for fans who are worried the trailer might have shown too much. According to sources at Universal, it looks like all that action we saw in the trailer is just taken from the first 57 minutes of the film. That means that the entire back half of the film is still a complete mystery.

It’s been four years since theme park and luxury resort Jurassic World was destroyed by dinosaurs out of containment. Isla Nublar now sits abandoned by humans while the surviving dinosaurs fend for themselves in the jungles.

When the island’s dormant volcano begins roaring to life, Owen (Chris Pratt) and Claire (Bryce Dallas Howard) mount a campaign to rescue the remaining dinosaurs from this extinction-level event. Owen is driven to find Blue, his lead raptor who’s still missing in the wild, and Claire has grown a respect for these creatures she now makes her mission. Arriving on the unstable island as lava begins raining down, their expedition uncovers a conspiracy that could return our entire planet to a perilous order not seen since prehistoric times.

With all of the wonder, adventure and thrills synonymous with one of the most popular and successful series in cinema history, this all-new motion-picture event sees the return of favorite characters and dinosaurs—along with new breeds more awe-inspiring and terrifying than ever before. Welcome to Jurassic World: Fallen Kingdom.
