When the Costa Rican Army begins bombing Isla Nublar in the aftermath of the Jurassic Park disaster, Dr. Alan Grant is in the middle of evacuating by helicopter — until he spots InGen operatives moving in by air. Convinced they intend to salvage dinosaur eggs and genetic material for a second attempt, Grant tries to alert the army before they can leave with anything. His pilot attempts to stop him from intervening, sending the helicopter down onto the very island Grant was fleeing. Alive in the wreckage, Grant must stay ahead of InGen's armed agents and stop them before the nightmare gets another chance to start.
