A motorcyclist crashes his bike and flies off a bridge over the ocean. He lands on a giant jellyfish that has surfaced. The jellyfish takes him out to sea where a navy ship rescues him. The ship is bound for a port city, one of the oldest in the world.
The captain tells the motorcyclist to go to the church and ask the priest there for help getting the motorcyclist home. The motorcyclist asks the priest if he can help the motorcyclist get back to his home and the priest says he’ll pay for the motorcyclist’s ship ticket if the motorcyclist pledges to read the holy book. The priest gives him the book and money for a ticket.
The motorcyclist goes to the docks and books passage with a merchant ship going to his home. The motorcyclist starts reading the book in his cabin but grows bored with it and decides he probably won’t finish it.
He goes to sleep and that night the ship is attacked. The motorcyclist wakes up to find that the ship is entangled in a massive jellyfish’s tendrils and is being dragged under. The motorcyclist jumps into the water and swims away. He swims to a small island nearby.
Over a few days wreckage comes ashore. The motorcyclist finds the book has washed ashore unharmed, cradled in wood debris that acted like a boat. He reads the book over and over.
Years pass and no one comes for the motorcyclist. Eventually he has read the book so much that he can recite it from memory. He begins to live in the ancient world the book refers to. That world is as vivid as the island he stands on.
One day the motorcyclist becomes sick and develops a fever. He watches the sun setting in the ocean. He walks into the water towards it. He feels a sting and sees the jellyfish tendrils floating about him in the water. He becomes numb and sinks under the surface.
