They need to go back to the original island where the park is. Maybe someone takes over InGen and decides to reboot the park.
The park is gone, in the book the Costa Rican government levelled it with missiles, in the Lost World film there is a deleted scene where John Hammond (CEO of InGen) nephew at a board meeting talks about how the Isla Nublar Facility (where the park was built) was dismantled and all the assets sold off.
I don't know in which direction they can take the film now, there is a plot thread about a rival company called Biosyn who have been trying for years to get Jurassic Park technology, mainly the DNA. It could be possible, like the Jurassic Park game, that Biosyn sent someone to the island the same day as a Plan B to find Nedry if he didn't turn up with the embryos.
The film could revolve around them finding Nedrys shaving foam can and manufacturing dinosaurs on the mainland and they all escape so the government brings in Alan, Ellie or other past characters back to hunt them down.
