The makers of Jurassic World: Fallen Kingdom have released some interesting details on the plot and have said Chris Pratt and Bryce Dallas Howard's characters will be seen reuniting for another action-packed dinosaur chase.

Directed by JA Bayona, the sequel of the 2015 billion-dollar smash Jurassic World centers around a volcano on Isla Nublar that threatens the dinosaurs that had overrun the park at the end of the previous film.

Dino trainer Owen Grady (played by Pratt) and Claire Dearing (played by Howard) will be seen jointly saving dinosaurs from volcanoes, according to a report in Entertainment Weekly.

Owen and former park manager Claire will spend the hour preventing the prehistoric beasts from becoming extinct again, the report added.

Elaborating more on the plot, Howard explained to EW, "Claire's founded an organisation, Dinosaur Protection Group, and they're finding a way to get these dinosaurs off the island.

"She reaches out to Owen Grady to let him know this is happening," added the actress, and teased a "complicated" relationship between her character and the Dino trainer.

She added, "When you see them at the beginning of this story, you get caught up as to what's going on. But it's not what you would necessarily expect."

Daniella Pineda and Justice Smith will play new characters involved with Claire's dino-saving group. Also, Jurassic Park legend Jeff Goldblum returns as mathematician Dr Ian Malcolm for the first time in 20 years.

Director Bayona said, "I had to overcome the impact of being in front of Ian Malcolm. After so many years, Jeff Goldblum was in front of a camera again talking about dinosaurs!"

Previously, the Thor Ragnarok actor said that his chaotician character from Jurassic Park will not be too happy with the use and misuse of technology. He told, "Ian Malcolm, yes, might be back in this one, and he might have something to say about the current confluence of circumstances around the use and misuse of technology.

"With some wry irony, deep wise passionate conviction, and he might put on a nice dark bit of clothing here and there... and a tint of glass maybe," he added.

The first trailer for the sequel will come out this Thursday (7 December), and will feature new dinosaur breeds which are more "awe-inspiring and terrifying than ever before".

The sequel hits theatres on 22 June, 2018.
