“Jurassic Park 4” won’t come roaring into theatres until 2015, but plot spoilers for the anticipated blockbuster have already hit the web. While director Colin Trevorrow revealed in May that the sequel will take place on the original films’ fictitious location of Isla Nublar, more details regarding the secretive plot lines were recently revealed.

According to movie blog JoeBlo via ComingSoon.net, “Jurassic Park 4” will start off during a period when dinosaurs and humans co-habitat on the island which is now a popular tourist destination. The alleged plot, revealed by what is being reported as a “trusted and reliable source,” dished that the film will feature the fictional dinosaur-inhabited island as safe, describing it as “Sea World-esque,” before tragedy ensues.

While the previous films have featured popular land-dinosaurs such as the infamous Tyrannosaurus Rex and the carnivorous velociraptors made famous by the series, this installment is said to feature prehistoric water animals. According to the report, one scene will feature a large acquatic dino jump out of its lagoon and eat a great white shark “like it was a fish for a dolphin at Sea World.”

While water creatures are rumored to be the feature of the flick currently in pre-production, one crowd favorite will be making reappearance. Velociraptors will be shown in the flick, this time wearing muzzles and will reportedly help fight against the threat—a new unnamed dinosaur which is said to be the demise of “Jurassic Park.” The film's latest villian is being described as "smarter than originally thought” and is said to “cause havoc breaking out at the park.”

The film, which was originally slated to be release in 2014, was recently pushed back to 2015 by filmmakers due to scheduling conflicts and script revisions reported Variety. The sequel will be the fourth film for the series but the first to be shot in 3D.
