...Flashback...
As Sarah landed into the waters, the crocodiles around grab her down into the depth when submarine from nowhere knocked off one of the crocodile and men dress in divers outfit swam toward the crocodiles that took Sarah.
The men who were with harpoon began to shot the hook into the body of creatures and scared them away.
One of the divers grabbed Sarah and they swam back into the submarine which moved away finally game to stop at a particular spot where it descend into the deepest part of the ocean and entered into an opening like cave.
A force from the cave was repelling the waters from entering.
The submarine finally stopped and the men swam out.
One of them carried Sarah and they all headed into the cave.
They got into a waiting elevator which travelled deep down into the ground and finally stopped.
