When the island with the remaining dinosaurs has a volcano about to explode a group of people try and rescue them but there are other forces at work. Chris Pratt and Bryce Dallas Howard reprise their roles from the previous film, trying to find a safe place for the donosaurs rather than exploiting them for money and military purposes. The first Jurassic Park film was a family film, but this fourth film in the francise is a more violent action film.
