Something has happened on land a few hours after the training ship Estrella Polar left the port; after a storm not foreseen in any maritime chart, all navigation systems have stopped working.

A global cataclysm, caused by a fatal accident floods the entire planet.

A plane crashes into the water a few meters from the ship; Vilma has problems with her pregnancy and needs to go to a hospital.

Julia tries to remain hopeful, and believes that there has to be land somewhere, but Ramiro is unable to accept what happened.

More than 40 thousand hungry birds are looking for land.

Hunger takes its toll on the temper and patience of students and teachers, and protests soon follow.
